t.colors was removed by #113; rendering threw on first iteration and
the theme grid rendered empty. Use the colors returned by
presetColors(t.id) instead. Verified in headless chromium: 5
theme-card elements render on /settings.
- Backend create/can validation paths emit machine-readable error codes
(slug_taken, slug_invalid, content_empty, content_too_large,
expiry_invalid, rate_limited, ...) alongside the human message
- new.html JS maps codes to plain-language guidance with generic fallback
- Result card colored via --ok/--err/--warn left border (result-ok/err/warn)
- docs/API.md error section documents the code field
- Tests assert the code on every validation path
Arrow is absolutely positioned at left:8px in the th, label padding-left
24px; translateY(-50%) keeps it centered regardless of row height, and
being out of flow the label never moves between sorted/unsorted states.
Panel was already display:none-gated until auth; tightened so a wrong
submitted key is never stored in sessionStorage — the typed key is
validated via the settings API first, and only persisted on 200.
