UI bug fix proof — reproduce the bug before claiming the fix

RED before GREEN — see ~/.claude/skills/evidence-standards/SKILL.md#ui-bug-fix-proof--environment-fidelity for the full checklist. Key rule: prove the bug is reproducible in the test environment first; verify the exact broken element (not its parent container); disclose any environment gaps (auth bypass, empty cache, JS-applied theme). "Tool compliant" (Playwright headless) ≠ "proof adequate" — the question is whether the test environment could reproduce the reported failure.
