Summary

New Admin → Appearance page to restyle the site without code. Changes are previewed live on the whole site for the admin only, until saved.

  • Theme: 6 presets (Trackarr, Midnight, Forest, Sunset, Monochrome, High contrast), per-token colour editing for light and dark themes, corner radius. Members still pick light/dark/system.
  • Typography: body, heading and mono fonts from a bundled set (IBM Plex, Inter, Space Grotesk, Nunito, Source Serif 4, JetBrains Mono, system). Bundled because the CSP only allows same-origin fonts; browsers only download the fonts in use.
  • Images: login page picture and home banner (PNG/JPEG/WebP checked by magic bytes, 8 MB, stored in the DB like logos, old file deleted on replace).
  • Login page: 4 designs (centered, split, background, minimal) with a live scaled preview. A new AuthShell component frames both sign-in and sign-up pages.
  • Texts: override any interface string per language, with search, "modified only" filter and the shipped text as placeholder.

How it works

  • One appearance setting, validated by shared/utils/appearance.ts (zod). Each section falls back to its default on its own.
  • Public GET /api/appearance; admin PUT /api/admin/appearance, POST /api/admin/appearance/image, GET /api/admin/appearance/texts?locale=.
  • app/plugins/appearance.ts injects a server-rendered <style> (no flash) built only from validated hex colours and enums. Fonts and radius are now CSS variables (tailwind.config.ts), defaults unchanged.
  • Text overrides are merged into vue-i18n as message functions: no runtime message compiler, @/{/| typed by an admin are never parsed as message syntax, output is escaped text. Only keys that exist in the shipped locale files are accepted (bundled as Nitro server assets); __proto__/constructor/prototype segments are rejected (a unit test caught a prototype-pollution path during development).

Notes

  • package-lock.json: npm also pruned optional peer deps of @nuxt/devtools (ioredis); this happens on any npm install with the current npm.
  • @fontsource/source-serif-4 pinned to 5.3.0 (5.3.1 is less than two weeks old).
  • Merge conflict expected with feat(torznab): dedicated api key and integrations page #93 on LOCALE_FILES in nuxt.config.ts (both add a file): keep both entries.

Test plan

  • npx vitest run: 286 passing, including 18 new appearance tests (schema, presets, CSS, override messages, prototype keys)
  • npm run build; locale files present in the server bundle
  • Dev: theme <style> rendered in SSR; a text override applies in SSR for its locale only, and disappears from SSR once removed (no leak across requests)
  • Dev, browser: the 4 login designs, presets, fonts and radius, in light and dark, no console errors
  • Admin endpoints return 401 without a session
  • Signed in as admin: walk through every tab of /admin/appearance, save, reload, upload/replace/remove both images, override a text in two languages

…d texts

Admins can now restyle the site from Admin → Appearance:
- theme presets and per-token colours for light and dark themes,
  corner radius
- body, heading and mono fonts from a bundled set
- login page picture and home banner
- four login designs (centered, split, background, minimal) with a
  live preview, shared by the sign-in and sign-up pages
- any interface text overridden per language

Everything lives in one validated `appearance` setting. The theme is
injected as a server-rendered <style>; text overrides are merged into
vue-i18n as message functions, so no runtime message compiler is
needed and admin text is never parsed as message syntax or HTML.

📝 Walkthrough

The change adds configurable appearance settings, an admin editor, server APIs and persistence, and runtime support for themes, text overrides, images, and authentication-page layouts.

Changes: Appearance customization

Layer / File(s) Summary
Appearance model and theme foundations
shared/utils/appearance.ts, app/assets/css/main.css, tailwind.config.ts, package.json, app/composables/useAppearance.ts, tests/appearance.test.ts
Shared types, defaults, validation, parsing, theme helpers, and text-override utilities define the appearance configuration. CSS uses configurable fonts and radius values. Tests cover the shared utilities.
Appearance persistence and APIs
server/utils/settings.ts, server/utils/localeSource.ts, server/api/appearance.get.ts, server/api/admin/appearance/*, server/api/admin/appearance/image.post.ts, server/api/admin/appearance/texts.get.ts, nuxt.config.ts
Settings helpers persist appearance data. Public and admin endpoints read or update settings, manage image uploads, and retrieve shipped locale text.
Admin appearance editor
app/components/admin/Appearance*.vue, app/pages/admin.vue, app/pages/admin/appearance.vue, i18n/locales/*/appearance.json, doc/guide/appearance.md, doc/.vitepress/config.ts, nuxt.config.ts
The admin page provides controls for themes, typography, images, login layouts, and text overrides. It supports draft previews, save and discard actions. Locale resources and the guide describe the editor.
Runtime appearance and authentication layouts
app/plugins/appearance.ts, app/pages/index.vue, app/components/AuthShell*.vue, app/pages/auth/login.vue, app/pages/auth/register.vue, app/utils/authBranding.ts
The plugin loads appearance settings and applies theme CSS and locale text overrides. The dashboard can render a configured banner. Login and registration pages use the shared authentication shell.

Merge Risk: 🟡 Moderate · up to 3c36c

The new text-override feature lets an admin-entered sign-in subtitle be rendered as raw HTML on the public login and registration pages, so it can run script for every visitor. Render or sanitize that subtitle as text before merging. A few smaller editor issues are worth fixing as well: overrides are accepted for keys that do not exist, edits made during a save can be lost, and pagination can show an empty page.

Inline comments:
Review comments at @app/components/admin/Appearance.vue:
- Around line 81-82: Update the save flow around the result assignments in
Appearance.vue so edits made while the PUT request is pending are not
overwritten by the older response. Either disable editing for the request
duration or retain and reapply changes made after the submitted draft, while
keeping saved.value synchronized with the confirmed result.
- Line 31: Update the appearance preview hint locale entries and the
corresponding promise in the appearance guide so they explicitly exclude image
changes and state when image updates become public. Keep the existing
private-preview wording for other appearance settings and update only the
affected text.

Review comments at @app/components/admin/AppearanceTexts.vue:
- Around line 106-108: Update the pagination logic near the computed pages and
page values to watch pages and clamp pageIndex to the highest valid page index
whenever the filtered list shrinks. Preserve the existing query, onlyModified,
and locale reset behavior, and keep pageIndex at zero when pages is one.

Review comments at @app/components/AuthShell.vue:
- Line 87: Update the subtitle handling in AuthShell so the fallback from
t('auth.defaultSubtitle') is rendered as plain text, or sanitize the final
subtitle before it reaches the existing v-html binding; preserve trusted
branding subtitle behavior while preventing unsanitized auth.defaultSubtitle
HTML from executing.

Review comments at @server/api/admin/appearance/index.put.ts:
- Line 22: Update the overrides filter in the appearance handler to use an
own-property check on source via Object.hasOwn instead of the
inherited-property-inclusive key in source check, while preserving the existing
non-empty text and changed-value conditions.

- escape the translated login subtitle before v-html: it is now an
  admin-editable text, not trusted markup
- accept text overrides for own keys of the shipped locales only, so
  inherited names like toString are rejected (keepTextOverrides, tested)
- lock the editor while saving so the response cannot drop newer edits
- clamp the texts page index when the filtered list shrinks
- say that images are public as soon as they are uploaded
