+Currently, HTML tags such as <em>, <strong>, <sup>, <a>, <ul>, and <li> are supported in Flowchart and Class diagram labels but not in Timeline diagrams. This change introduces support for basic HTML formatting in Timeline labels, enabling richer text formatting and better usability for multi-line content like descriptions, footnotes, and styled annotations

-# 🎯 ANTLR Parser Setup & Testing Guide
-
-This guide explains how to use the ANTLR parser system for Mermaid diagrams and test it in the development environment. The system supports multiple diagram types with a unified generation and testing workflow.
-
-## 🚀 Quick Start
-
-### 1. Automatic Generation (Recommended)
-
-ANTLR files are **automatically generated** during:
-
-```bash
-# Fresh installation - ANTLR files generated automatically
-pnpm install
-
-# Build process - ANTLR files regenerated automatically
-pnpm build
-
-# Development server - ANTLR files generated + watched
-pnpm dev:antlr
-```
-
-### 2. Manual Generation (Optional)
-
-```bash
-# Generate ANTLR parser files for ALL supported diagrams
-pnpm antlr:generate
-```
-
-This single command automatically:
-
-- 🔍 **Discovers** all `.g4` grammar files across diagram types
-- 🧹 **Cleans** existing generated directories
-- 📁 **Creates** generated directories if needed
-- ⚡ **Generates** ANTLR parser files for all diagrams
-- 📊 **Reports** success/failure summary
-
-### 3. Grammar Development (Watch Mode)
-
-```bash
-# Generate + watch grammar files for changes
-pnpm antlr:watch
-```
-
-**Perfect for grammar development:**
-
-- ✅ **Initial generation** of all ANTLR files
-- ✅ **File watching** - Monitors `.g4` files for changes
-- ✅ **Auto-regeneration** - Rebuilds when grammar files change
-- ✅ **Debounced updates** - Prevents multiple rapid rebuilds
-- ✅ **Clear logging** - Shows which files changed and generation progress
-- ✅ **Graceful shutdown** - Ctrl+C to stop watching
-
-### 4. Start Development Server with ANTLR Parser
-
-```bash
-# Start dev server with ANTLR parser enabled + file watching
-pnpm dev:antlr
-```
-
-**Features:**
-
-- ✅ **ANTLR files generated** on startup
-- ✅ **Grammar file watching** - `.g4` files trigger auto-regeneration
-- ✅ **Hot reload** - Changes rebuild automatically
-- ✅ **All diagram types** supported
-
-### 5. Test ANTLR Parser
-
-Open your browser to test different diagram types:
-
-- **Flowchart ANTLR Test**: http://localhost:9000/flowchart-antlr-test.html
-- **Regular Flowchart Demo**: http://localhost:9000/flowchart.html
-- **Sequence Diagram Demo**: http://localhost:9000/sequence.html
-
-## 🏗️ Build Integration
-
-ANTLR generation is fully integrated into the build pipeline:
-
-### **Automatic Generation Points**
-
-| Command          | When ANTLR Runs            | Purpose                                |
-| ---------------- | -------------------------- | -------------------------------------- |
-| `pnpm install`   | **postinstall hook**       | Ensure files exist after fresh install |
-| `pnpm build`     | **build process**          | Regenerate before building packages    |
-| `pnpm dev:antlr` | **server startup + watch** | Development with auto-regeneration     |
-
-### **Build Process Flow**
-
-```mermaid
-graph TD
-    A[pnpm install] --> B[postinstall hook]
-    B --> C[ANTLR Generation]
-    C --> D[prepare hook]
-    D --> E[Build Process]
-    E --> F[Langium Generation]
-    F --> G[ANTLR Generation]

-
-    J[pnpm build] --> F
-    K[pnpm dev:antlr] --> L[Watch .g4 files]
-    L --> G
-```
-
-### **Smart Path Detection**
-
-The ANTLR generator works from any directory:
-
-```bash
-# From project root
-pnpm antlr:generate  # Uses: packages/mermaid/src/diagrams
-
-# From mermaid package
-cd packages/mermaid
-pnpm antlr:generate  # Uses: src/diagrams
-```
-

-
-## 🏗️ Dual-Pattern Architecture
-
-The ANTLR parser supports both Listener and Visitor patterns with identical behavior:
-
-### 👂 Listener Pattern
-
-- **Event-driven**: Parser controls traversal via enter/exit methods
-- **Push-based**: Parser pushes events to listener callbacks
-- **Automatic traversal**: Uses `ParseTreeWalker.DEFAULT.walk()`
-- **Best for**: Simple processing, event-driven architectures
-
-### 🚶 Visitor Pattern (Default)
-
-- **Pull-based**: Developer controls traversal and can return values
-- **Manual traversal**: Uses `visitor.visit()` and `visitChildren()`
-- **Return values**: Can return data from visit methods
-- **Best for**: Complex processing, data transformation, AST manipulation
-
-### 🔄 Shared Core Logic
-
-Both patterns extend `FlowchartParserCore` which contains:
-
-- All parsing logic that achieved 99.1% test compatibility
-- Shared helper methods for node processing, style handling, etc.
-- Database interaction methods
-- Error handling and validation
-
-This architecture ensures **identical behavior** regardless of pattern choice.
-
-## ⚡ Performance Optimizations
-
-### 🚀 Low-Hanging Fruit Optimizations (15% Improvement)
-
-The ANTLR parser includes several performance optimizations:
-
-#### **1. Conditional Logging**
-
-- Only logs for complex diagrams (>100 edges) or when `ANTLR_DEBUG=true`
-- Dramatically reduces console noise for normal operations
-- Maintains detailed debugging when needed
-
-#### **2. Optimized Performance Tracking**
-
-- Performance measurements only enabled in debug mode
-- Reduced `performance.now()` calls for frequently executed methods
-- Streamlined progress reporting frequency
-
-#### **3. Efficient Database Operations**
-
-- Conditional logging for vertex/edge creation
-- Optimized progress reporting (every 5000-10000 operations)
-- Reduced overhead for high-frequency operations
-
-#### **4. Debug Mode Support**
-
-```bash
-# Enable full detailed logging
-ANTLR_DEBUG=true pnpm dev:antlr
-
-# Normal operation (clean output)
-pnpm dev:antlr
-```
-
-### 📊 Performance Results
-
-| Test Size                 | Before Optimization | After Optimization | Improvement    |
-| ------------------------- | ------------------- | ------------------ | -------------- |
-| **Medium (1000 edges)**   | 2.64s               | 2.25s              | **15% faster** |
-| **Parse Tree Generation** | 2455ms              | 2091ms             | **15% faster** |
-| **Tree Traversal**        | 186ms               | 154ms              | **17% faster** |
-
-### 🎯 Performance Characteristics
-
-- **Small diagrams** (<100 edges): ~50-200ms parsing time
-- **Medium diagrams** (1000 edges): ~2.2s parsing time
-- **Large diagrams** (10K+ edges): May require grammar-level optimizations
-- **Both patterns perform identically** with <3% variance
-
-## 🔍 Debugging
-
-### Browser Console
-
-The test page provides detailed console logging:
-
-- Environment variable status
-- Parser selection confirmation
-- Diagram rendering status
-- Error detection and reporting
-
-### Server Logs

-
-## 🚨 Troubleshooting
-
-### **Build & Generation Issues**
-
-1. **Missing ANTLR files after install**
-
-   ```bash
-   # Manually regenerate
-   pnpm antlr:generate
-
-   # Check if postinstall ran
-   pnpm install --force
-   ```
-
-2. **Generation fails during build**
-
-   ```bash
-   # Check antlr-ng installation
-   which antlr-ng
-
-   # Reinstall if missing
-   pnpm install -g antlr4ng
-   ```
-
-3. **No grammar files found**
-
-   - Ensure `.g4` files are in correct location: `src/diagrams/*/parser/antlr/*.g4`
-   - Check file naming convention: `*Lexer.g4`, `*Parser.g4`
-   - Verify you're running from correct directory
-
-4. **Permission errors during generation**
-   ```bash
-   # Fix permissions
-   chmod -R 755 packages/mermaid/src/diagrams/*/parser/antlr/
-   ```
-
-### **Development Issues**
-
-5. **ANTLR parser not being used**: Check environment variable `USE_ANTLR_PARSER=true`
-6. **Environment variable not set**: Use `pnpm dev:antlr` instead of `pnpm dev`
-7. **Diagrams not rendering**: Check browser console for parsing errors
-8. **Watch not working**:
-   - For dev server: Restart with `pnpm dev:antlr`
-   - For grammar development: Use `pnpm antlr:watch` instead
-
-### **Grammar Issues**
-
-9. **ANTLR generation warnings**
-
-   - Check grammar file syntax with ANTLR tools
-   - Compare with working examples in existing diagrams
-   - Warnings are usually non-fatal but should be addressed
-
-10. **Generated files not updating**
-    ```bash
-    # Force clean regeneration
-    rm -rf packages/mermaid/src/diagrams/*/parser/antlr/generated
-    pnpm antlr:generate
-    ```
-
-### **Getting Help**
-
-- **Console Output**: Check detailed error messages in terminal
-- **Browser Console**: Look for parsing errors during development
-- **Grammar Validation**: Use ANTLR tools to validate `.g4` files
-- **Compare Examples**: Reference working implementations in existing diagrams
-- **Build Logs**: Review server logs for build issues
-- **Fresh Start**: Try `pnpm install --force` for clean installation

-2. **Generate ANTLR Files**
-
-   ```bash
-   pnpm antlr:generate  # Automatically detects new grammars
-   ```
-
-3. **Implement Architecture**
-
-   - Create `[Diagram]ParserCore.ts` with shared logic
-   - Create `[Diagram]Listener.ts` extending core
-   - Create `[Diagram]Visitor.ts` extending core
-   - Update main parser with pattern selection
-
-4. **Test and Validate**
-   - Run regression tests
-   - Achieve high compatibility with existing Jison parser
-   - Validate both Listener and Visitor patterns
-
-The generic ANTLR generation system will automatically handle the new diagram type!

-## 🎯 Generic ANTLR Generation System
-
-### **How It Works**
-
-#### 1. **Auto-Discovery**
-
-The script automatically finds all `.g4` files in:
-
-```
-packages/mermaid/src/diagrams/*/parser/antlr/*.g4
-```
-
-#### 2. **Grammar Pairing**
-
-For each diagram, it looks for:
-
-- `*Lexer.g4` - Lexical analyzer grammar
-- `*Parser.g4` - Parser grammar
-
-#### 3. **Generation Process**
-
-For each valid grammar pair:
-
-1. Clean the `generated/` directory
-2. Create the directory if needed
-3. Run `antlr-ng` with TypeScript target
-4. Generate all necessary files
-
-#### 4. **Generated Files**
-
-Each diagram gets these generated files:
-
-- `*Lexer.ts` - Lexer implementation
-- `*Parser.ts` - Parser implementation
-- `*ParserListener.ts` - Listener interface
-- `*ParserVisitor.ts` - Visitor interface
-- `*.tokens` - Token definitions
-- `*.interp` - ANTLR interpreter files
-
-### **Supported Diagrams**
-
-| Diagram Type  | Grammar Files                           | Generated Location                                                |
-| ------------- | --------------------------------------- | ----------------------------------------------------------------- |
-| **Flowchart** | `FlowLexer.g4`, `FlowParser.g4`         | `packages/mermaid/src/diagrams/flowchart/parser/antlr/generated/` |
-| **Sequence**  | `SequenceLexer.g4`, `SequenceParser.g4` | `packages/mermaid/src/diagrams/sequence/parser/antlr/generated/`  |
-| **Class**     | `ClassLexer.g4`, `ClassParser.g4`       | `packages/mermaid/src/diagrams/class/parser/antlr/generated/`     |
-
-### **Example Output**
-
-```bash
-🚀 ANTLR Generator - Finding and generating all grammar files...
-

-# Layouts
-
-This page lists the available layout algorithms supported in Mermaid diagrams.
-
-## Supported Layouts
-
-- **elk**: [ELK (Eclipse Layout Kernel)](https://www.eclipse.org/elk/)
-- **tidy-tree**: Tidy tree layout for hierarchical diagrams [Tidy Tree Configuration](/config/tidy-tree)
-- **cose-bilkent**: Cose Bilkent layout for force-directed graphs
-- **dagre**: Dagre layout for layered graphs
-
-## How to Use
-
-You can specify the layout in your diagram's YAML config or initialization options. For example:
-
-```mermaid-example
----
-config:
-  layout: elk
----
-graph TD;
-  A-->B;
-  B-->C;
-```
-
-```mermaid
----
-config:
-  layout: elk
----
-graph TD;
-  A-->B;
-  B-->C;
-```

-# Tidy-tree Layout
-
-The **tidy-tree** layout arranges nodes in a hierarchical, tree-like structure. It is especially useful for diagrams where parent-child relationships are important, such as mindmaps.
-
-## Features
-
-- Organizes nodes in a tidy, non-overlapping tree
-- Ideal for mindmaps and hierarchical data
-- Automatically adjusts spacing for readability
-
-## Example Usage

-## Tidy Tree Layout Overview
-
-tidy-tree: The bidirectional tidy tree layout
-
-The bidirectional tidy tree layout algorithm creates two separate trees that grow horizontally in opposite directions from a central root node:
-Left tree: grows horizontally to the left (children alternate: 1st, 3rd, 5th...)
-Right tree: grows horizontally to the right (children alternate: 2nd, 4th, 6th...)
-
-This creates a balanced, symmetric layout that is ideal for mindmaps, organizational charts, and other tree-based diagrams.
-
-Layout Structure:
-[Child 3] ← [Child 1] ← [Root] → [Child 2] → [Child 4]
-↓ ↓ ↓ ↓
-[GrandChild] [GrandChild] [GrandChild] [GrandChild]

- * Bidirectional Tidy-Tree Layout Algorithm for Generic Diagrams
- *
- * This module provides a layout algorithm implementation using the

- * in tree structures with a bidirectional approach.
- *
- * The algorithm creates two separate trees that grow horizontally in opposite
- * directions from a central root node:
- * - Left tree: grows horizontally to the left (children alternate: 1st, 3rd, 5th...)
- * - Right tree: grows horizontally to the right (children alternate: 2nd, 4th, 6th...)
- *
- * This creates a balanced, symmetric layout that is ideal for mindmaps,
- * organizational charts, and other tree-based diagrams.
- *
- * The algorithm follows the unified rendering pattern and can be used
- * by any diagram type that provides compatible LayoutData.
- */
-
-/**
- * Render function for the bidirectional tidy-tree layout algorithm
- *
- * This function follows the unified rendering pattern used by all layout algorithms.
- * It takes LayoutData, inserts nodes into DOM, runs the bidirectional tidy-tree layout algorithm,
- * and renders the positioned elements to the SVG.
- *
- * Features:
- * - Alternates root children between left and right trees
- * - Left tree grows horizontally to the left (rotated 90° counterclockwise)
- * - Right tree grows horizontally to the right (rotated 90° clockwise)
- * - Uses tidy-tree algorithm for optimal spacing within each tree
- * - Creates symmetric, balanced layouts
- * - Maintains proper edge connections between all nodes
- *
- * Layout Structure:
- * ```
- * [Child 3] ← [Child 1] ← [Root] → [Child 2] → [Child 4]
- *     ↓           ↓                     ↓           ↓

-## ANTLR migration plan for Class Diagrams (parity with Sequence)
-
-This guide summarizes how to migrate the Class diagram parser from Jison to ANTLR (antlr4ng), following the approach used for Sequence diagrams. The goal is full feature parity and 100% test pass rate, while keeping the Jison implementation as the reference until the ANTLR path is green.
-
-### Objectives
-
-- Keep the existing Jison parser as the authoritative reference until parity is achieved
-- Add an ANTLR parser behind a runtime flag (`USE_ANTLR_PARSER=true`), mirroring Sequence
-- Achieve 100% test compatibility with the current Jison behavior, including error cases
-- Keep the public DB and rendering contracts unchanged
-
----
-
-## 1) Prep and references
-
-- Use the Sequence migration as a template for structure, scripts, and patterns:
-  - antlr4ng grammar files: `SequenceLexer.g4`, `SequenceParser.g4`
-  - wrapper: `antlr-parser.ts` providing a Jison-compatible `parse()` and `yy`
-  - generation script: `pnpm --filter mermaid run antlr:sequence`
-- For Class diagrams, identify analogous files:
-  - Jison grammar: `packages/mermaid/src/diagrams/class/parser/classDiagram.jison`
-  - DB: `packages/mermaid/src/diagrams/class/classDb.ts`
-  - Tests: `packages/mermaid/src/diagrams/class/classDiagram.spec.js`
-- Confirm Class diagram features in the Jison grammar and tests: classes, interfaces, enums, relationships (e.g., `--`, `*--`, `o--`, `<|--`, `--|>`), visibility markers (`+`, `-`, `#`, `~`), generics (`<T>`, nested), static/abstract indicators, fields/properties, methods (with parameters and return types), stereotypes (`<< >>`), notes, direction, style/config lines, and titles/accessibility lines if supported.
-
----
-
-## 2) Create ANTLR grammars
-
-- Create `ClassLexer.g4` and `ClassParser.g4` under `packages/mermaid/src/diagrams/class/parser/antlr/`
-- Lexer design guidelines (mirror Sequence approach):
-  - Implement stateful lexing with modes to replicate Jison behavior (e.g., default, line/rest-of-line, config/title/acc modes if used)
-  - Ensure token precedence resolves conflicts between relation arrows and generics (`<|--` vs `<T>`). Prefer longest-match arrow tokens and handle generics in parser context
-  - Accept identifiers that include special characters that Jison allowed (quotes, underscores, digits, unicode as applicable)
-  - Provide tokens for core keywords and symbols: `class`, `interface`, `enum`, relationship operators, visibility markers, `<< >>` stereotypes, `{ }` blocks, `:` type separators, `,` parameter separators, `[` `]` arrays, `<` `>` generics
-  - Reuse common tokens shared across diagrams where appropriate (e.g., `TITLE`, `ACC_...`) if Class supports them
-- Parser design guidelines:
-  - Follow the Jison grammar structure closely to minimize semantic drift
-  - Allow the final statement in the file to omit a trailing newline (to avoid EOF vs NEWLINE mismatches)
-  - Keep non-ambiguous rules for:
-    - Class declarations and bodies (members split into fields/properties vs methods)
-    - Modifiers (visibility, static, abstract)
-    - Types (simple, namespaced, generic with nesting)
-    - Relationships with labels (left->right/right->left forms) and multiplicities
-    - Stereotypes and notes
-    - Optional global lines (title, accTitle, accDescr) if supported by class diagrams
-
----
-
-## 3) Add the wrapper and flag switch
-
-- Add `packages/mermaid/src/diagrams/class/parser/antlr/antlr-parser.ts`:
-  - Export an object `{ parse, parser, yy }` that mirrors the Jison parser shape
-  - `parse(input)` should:
-    - `this.yy.clear()` to reset DB (same as Sequence)
-    - Build ANTLR's lexer/parser, set `BailErrorStrategy` to fail-fast on syntax errors
-    - Walk the tree with a listener that calls classDb methods
-  - Implement no-op bodies for `visitTerminal`, `visitErrorNode`, `enterEveryRule`, `exitEveryRule` (required by ParseTreeWalker)
-  - Avoid `require()`; import from `antlr4ng`
-  - Use minimal `any`; when casting is unavoidable, add clear comments
-- Add `packages/mermaid/src/diagrams/class/parser/classParser.ts` similar to Sequence `sequenceParser.ts`:
-  - Import both the Jison parser and the ANTLR wrapper
-  - Gate on `process.env.USE_ANTLR_PARSER === 'true'`
-  - Normalize whitespace if Jison relies on specific newlines (keep parity with Sequence patterns)
-
----
-
-## 4) Implement the listener (semantic actions)
-
-Map parsed constructs to classDb calls. Typical handlers include:
-
-- Class-like declarations
-  - `db.addClass(id, { type: 'class'|'interface'|'enum', ... })`
-  - `db.addClassMember(id, member)` for fields/properties/methods (capture visibility, static/abstract, types, params)
-  - Stereotypes, annotations, notes: `db.addAnnotation(...)`, `db.addNote(...)` if applicable
-- Relationships
-  - Parse arrow/operator to relation type; map to db constants (composition/aggregation/inheritance/realization/association)
-  - `db.addRelation(lhs, rhs, { type, label, multiplicity })`
-- Title/Accessibility (if supported in Class diagrams)
-  - `db.setDiagramTitle(...)`, `db.setAccTitle(...)`, `db.setAccDescription(...)`
-- Styles/Directives/Config lines as supported by the Jison grammar
-
-Error handling:
-
-- Use BailErrorStrategy; let invalid constructs throw where Jison tests expect failure
-- For robustness parity, only swallow exceptions in places where Jison tolerated malformed content without aborting
-
----
-
-## 5) Scripts and generation
-
-- Add package scripts similar to Sequence in `packages/mermaid/package.json`:
-  - `antlr:class:clean`: remove generated TS
-  - `antlr:class`: run antlr4ng to generate TS into `parser/antlr/generated`
-- Example command (once scripts exist):
-  - `pnpm --filter mermaid run antlr:class`
-
----
-
-## 6) Tests (Vitest)
-
-- Run existing Class tests with the ANTLR parser enabled:
-  - `USE_ANTLR_PARSER=true pnpm vitest packages/mermaid/src/diagrams/class/classDiagram.spec.js --run`
-- Start by making a small focused subset pass, then expand to the full suite
-- Add targeted tests for areas where the ANTLR grammar needs extra coverage (e.g., nested generics, tricky arrow/operator precedence, stereotypes, notes)
-- Keep test expectations identical to Jison’s behavior; only adjust if Jison’s behavior was explicitly flaky and already tolerated in the repo
-
----
-
-## 7) Linting and quality
-
-- Satisfy ESLint rules enforced in the repo:
-  - Prefer imports over `require()`; no empty methods, avoid untyped `any` where reasonable
-  - If `@ts-ignore` is necessary, include a descriptive reason (≥10 chars)
-- Provide minimal types for listener contexts where helpful; keep casts localized and commented
-- Prefix diagnostic debug logs with the project’s preferred prefix if temporary logging is needed (and clean up before commit)
-
----
-
-## 8) Common pitfalls and tips
-
-- NEWLINE vs EOF: allow the last statement without a trailing newline to prevent InputMismatch
-- Token conflicts: order matters; ensure relationship operators (e.g., `<|--`, `--|>`, `*--`, `o--`) win over generic `<`/`>` in the right contexts
-- Identifiers: match Jison’s permissiveness (quoted names, digits where allowed) and avoid over-greedy tokens that eat operators
-- Listener resilience: ensure classes and endpoints exist before adding relations (create implicitly if Jison did so)
-- Error parity: do not swallow exceptions for cases where tests expect failure
-
----
-
-## 9) Rollout checklist
-
-- [ ] Grammar compiles and generated files are committed
-- [ ] `USE_ANTLR_PARSER=true` passes all Class diagram tests
-- [ ] Sequence and other diagram suites remain green
-- [ ] No new ESLint errors; warnings minimized
-- [ ] PR includes notes on parity and how to run the ANTLR tests
-
----
-
-## 10) Quick command reference
-
-- Generate ANTLR targets (after adding scripts):
-  - `pnpm --filter mermaid run antlr:class`
-- Run Class tests with ANTLR parser:
-  - `USE_ANTLR_PARSER=true pnpm vitest packages/mermaid/src/diagrams/class/classDiagram.spec.js --run`
-- Run a single test:
-  - `USE_ANTLR_PARSER=true pnpm vitest packages/mermaid/src/diagrams/class/classDiagram.spec.js -t "some test name" --run`
