What changed

OpenROM themes (.orskin) become a first-class storefront category next to the
executable extensions, with live colour swatches on the cards and a palette
inspector plus mockup preview on the detail page.

                                                          Inspector + Apply in OpenROM

No schema change was needed. A theme is an ordinary plugins row with
category = 'Themes', reusing the columns that normally describe conversion
tooling:

Column	For a plugin	For a theme
routes_json	["ISO -> WUA"]	["#0d0e15","#161926","#e94560","#00f0ff","#ffffff"]
platforms_json	["Windows","Linux"]	["All Platforms"]

The palette is read positionally as Background, Surface, Accent and Text.

Security: the palette is untrusted input

Those hex strings come from D1 and are rendered into style attributes, so
without validation a crafted palette could break out of the attribute.
src/lib/theme.ts validates every colour against #rgb/#rgba/#rrggbb/#rrggbbaa
and drops anything else before it can reach a template:

const HEX_COLOR = /^#(?:[0-9a-f]{3}|[0-9a-f]{4}|[0-9a-f]{6}|[0-9a-f]{8})$/i;

I verified this at runtime by writing a malicious palette into D1
(["#0d0e15","red;}body{display:none","url(javascript:alert(1))","#00f0ff"])
and parsing the rendered HTML: the two valid colours render, the two payloads
are dropped, and no injected element or attribute ever appears. contrastText
picks a readable foreground by relative luminance so the preview stays legible
on any palette.

Verification

Notes

• The launch theme Cyberpunk Neon 1.0.0 by M5 Dev is registered by data
  migration 0006 and ships at public/themes/cyberpunk-neon.orskin; the
  migration records that file's real SHA-256.
• The download URL is root-relative (/themes/cyberpunk-neon.orskin). The
  task suggested an absolute https://openrom-store.pages.dev/... URL, but a
  relative Location works identically in production while also working on
  Cloudflare preview deployments and local wrangler pages dev — an absolute
  hostname would break the last two. Easy to change if you'd rather pin it.
• The task's seed listed publisher_id: m5dev while the description said
  "publisher_id: m5dev" / "publisher_name: M5 Dev" — I used m5dev (matching
  migration 0005's publisher row) with display name M5 Dev.

Walkthrough

The change adds the Cyberpunk Neon theme to the catalog and skin files. Theme helpers validate and map palette colors, and storefront cards and plugin pages provide theme-specific previews, apply links, downloads, and installation instructions.

Changes: Cyberpunk Neon theme support

Layer / File(s)	Summary
Theme package and catalog registration public/themes/cyberpunk-neon.orskin, migrations/0006_cyberpunk_neon_theme.sql	Adds the Cyberpunk Neon skin configuration and registers its publisher and plugin record. The upsert refreshes plugin fields without changing an existing download count.
Theme helpers and category labels src/lib/theme.ts, src/lib/site.ts, tests/theme.test.ts	Adds theme detection, color validation, palette and swatch mapping, contrast text selection, URI and filename helpers, and category labels. Tests cover the theme helpers and constants.
Theme-aware catalog cards src/components/Card.astro, src/components/CategoryFilter.astro, src/components/Icon.astro, src/lib/site.ts	Catalog cards show theme swatches and theme-specific copy and download labels. Category controls use formatted category labels. The icon map adds a palette icon, and platform icons include an all-platforms entry.
Theme plugin detail page src/pages/plugin/[id].astro	Theme pages expose a palette manifest, render a palette preview and inspector, and provide theme-specific apply, download, and installation instructions. Non-theme plugin flows remain available.

Include all-platform themes in platform filters

When a user selects Windows, Linux, or macOS, the exact-match filter hides Cyberpunk Neon. Treat All Platforms as a match for each selected platform.

Suggested fix

In src/pages/index.astro:

       const matchesPlatform =
-        state.platforms.size === 0 || platforms.some((p) => state.platforms.has(p));
+        state.platforms.size === 0 ||
+        platforms.includes('All Platforms') ||
+        platforms.some((p) => state.platforms.has(p));
