safari-fix — Static scan + fix for Safari/WebKit pitfalls

Find pitfalls — code patterns that render or run fine in Chrome but break in Safari (WebKit) — by static analysis. No browser is launched; the code is the only input. Each pitfall carries a confidence tier that decides the action:

• [auto-fix] — the fix is safe with no side effects. Apply it directly.
• [report-only] — false-positive risk, or the fix requires a design / browser-support decision. Do not touch; report it.

Grep patterns, verdict criteria, fixes, and confidence tiers for every pitfall live in PITFALLS.md.

1. Scope

If a file/directory path is given as an argument, scan only that. Otherwise use the files being worked on in the conversation; failing that, all frontend files in the repository (css/js/html). List the target files at the top of the report.

2. Scan

Grep the target files for every item in PITFALLS.md.

Completion criterion: every item is recorded as either "hit (file:line)" or "not present". Do not move on with items skipped.

3. Verdict — filter false positives

A grep hit is a candidate, not a pitfall. For each hit, read the actual code at that location and check the verdict criteria (surrounding conditions) in PITFALLS.md. Example: 100vh is a pitfall only on fixed full-screen elements; in a desktop-only section it is harmless.

Completion criterion: every hit is recorded as confirmed / false positive / undecidable (with reason).

4. Fix

• Fix [auto-fix] items only. Follow the surrounding code's style and comment conventions (e.g. this repo's CSS block-comment rule). Where a comment is warranted, state the WebKit issue in one line.
• Do not touch [report-only] items — put the decision they need (browser-support range, design impact) as a question in the report.
• Do not touch code unrelated to a pitfall. Every changed line must trace back to a specific pitfall.

5. Report

## safari-fix results — <scope>

| Pitfall | Location | Verdict | Action |
|---|---|---|---|
| svg width missing from shrink-to-fit | product-detail.css:3042 | confirmed | ✅ added min-width |
| input font-size <16px (iOS zoom) | product-detail.css:812 | confirmed | ⚠️ report-only — design decision needed |

- Hits dismissed as false positives: (location + reason)
- Decisions needed from the user: (questions from report-only items)

Static analysis is inference without reproduction — end the report by recommending verification in real Safari (live verification is out of scope for this skill).
