1️⃣ Wrapper auto-injects title + phase badge + CSS on first load and watches for change of phase on badge.

2️⃣ More than one diagram confuses system. For now, only one per md in order to run.

3️⃣ Checks and publication depend on what and where final product goes, so it's user discretion.

Numbered Notes (1️⃣ 2️⃣ 3️⃣)

When to use:

Pre-execution (design phase):

• Questions that need discussion
• Trade-offs that need decisions
• Unclear requirements

During execution:

• Errors AI can't resolve alone
• Permission needed (destructive action, cost implications)
• Ambiguity in implementation

Format:

### 1️⃣ [Component Name] - [Issue Title]
**Question/Error:** ...
**Context:** ...
**Options:** A, B, C
**Needed:** Decision / Permission / Help

Notes without numbers = just explanations, turn yellow when approved.
