Generate a detailed project timeline in Gantt chart format showing task durations, dependencies, milestones, team assignments, and the critical path so stakeholders can visualize the full project schedule at a glance.

PROJECT TIMELINE INSTRUCTIONS:
1. Parse the provided phases, tasks, milestones, and dependencies.
2. For each task, determine:
   - Start and end dates (based on dependencies and phase sequencing)
   - Duration in business days
   - Assigned team member or role (for color coding)
   - Dependency links (which tasks must complete first)
3. Identify the CRITICAL PATH: the longest chain of dependent tasks that determines the minimum project duration. Highlight these tasks.
4. Mark milestones with diamond markers at their target dates.
5. Build the Gantt chart with:
   - Rows: one per task, grouped under phase headers
   - Columns: time units (days or weeks, chosen automatically based on project length)
   - Task bars showing duration, with fill or shading to indicate assigned team member
   - Dependency arrows connecting predecessor tasks to successors
   - Milestone diamonds on the appropriate dates
   - A "Today" marker line if the project is already underway
6. Provide a summary section below the chart:
   - Total project duration
   - Critical path tasks listed in order
   - Resource allocation overview (who is busiest and when)
   - Schedule risk areas (tasks with zero slack, resource conflicts, or tight turnarounds)

OUTPUT FORMAT:
- Default: ASCII/text-based Gantt chart suitable for pasting into documents, wikis, or chat.
- If requested, provide Mermaid.js gantt syntax that can be rendered in tools like GitHub, Notion, or Mermaid Live Editor.

OUTPUT CONSTRAINTS:
- Keep task names short (under 40 characters) in the chart for readability.
- Use consistent date formatting (YYYY-MM-DD).
- Color-code or label team assignments clearly.
- Flag any scheduling conflicts or impossible dependency chains with "[WARNING]".
- If information is incomplete (e.g., missing durations), make reasonable assumptions and mark them with "[EST]".
