The form only enforced the length cap, so CSS with an external url() or @import
passed client validation and was rejected by the server. Add the same tokenizer
based check with the same error message so it is caught inline before submit.
Bound customCSS to 100000 characters on both the client schema and the
server body validation (the server is the enforcement boundary; multer's
1MB field cap was the only limit), regenerate the OpenAPI spec, and add
a validation test suite covering acceptance, clearing, the length cap,
and type rejection.
Adds four fully-designed visual themes for the public status page
(refined | modern | bold | editorial) with a light/dark mode selector,
admin preview in a mock browser frame, and a shared theme provider
that keeps the component tree unified while letting each theme own
its visual identity.
## Selectable themes
- Refined — clean, flat cards, soft shadows, colored status dot.
- Modern — flat surfaces with a pulsing status dot and staggered
fade-in cards.
- Bold — conic-gradient logo, 34px hero title with a check disc,
subtle dual-radial glow on dark mode, accent-green hover border.
- Editorial — serif headings, narrow newspaper column, 'Service
Report' eyebrow + title, flat rectangular badges and dateline.
## Architecture
- Single `StatusPageThemeProvider` hosts CSS custom-property tokens
per theme and resolves light/dark based on admin-forced mode,
falling back to `prefers-color-scheme` with a matchMedia listener.
- Each theme owns only its `*StatusPage.tsx` + scoped CSS file.
The heatmap, histogram, and infrastructure renderers are shared
across all four themes (parameterized by a `classPrefix`) to avoid
the 12-file duplication the initial draft had.
- Renderer lookup table in `Status/index.tsx` replaces a 4-way
ternary chain; unknown themes fall through to the legacy renderer.
- `resolveOverallStatus`, `statusBadgeKey`, `monoFirstChar`, and
`monitorBadgeTone` are extracted to `themes/shared/overallStatus.tsx`.
## Admin UX
- `ThemePicker` uses the project's `RadioWithDescription` and
`Select` components — one radio card per theme plus an Auto/
Light-only/Dark-only mode dropdown.
- `BrowserFrame` wraps the preview in the admin panel with a mock
chrome (traffic lights + URL bar) that adopts the status page's
theme tokens. Edge-to-edge fill with no gray bleed.
- Public route renders the theme directly on the viewport with the
document body painted to the theme background, reverted on unmount.
## Performance & polish
- Histogram's derived stats (padded array, max, avg, peak) are
memoized on `checks`; `max` is reused for `peak` instead of
computing twice.
- Editorial's dateline is wrapped in `useMemo` so the 10s poll
doesn't rerender "April 23, 2026" as a changing string.
- Provider's `setSystemMode` reconciliation uses the updater form
to avoid an extra render when the value is unchanged.
- `monoFirstChar` no longer uses a non-null assertion.
## Form plumbing
- `useStatusPageForm` defaults include `theme` + `themeMode`.
- `Validation/statusPage.ts` accepts both as optional zod enums.
- `Pages/StatusPage/Create/index.tsx` appends both to FormData on
create and update.

- Dev port note: local client runs on 10001 (5173 is used by a
different local project); server `CLIENT_HOST` is set to match.
