Add extensible site theme system with Christmas theme

Open Copilot opened this issue 2 months ago • 0 comments

Motivation and Context

Enable admins to activate seasonal themes (e.g., Christmas) site-wide for all users, with an extensible architecture for adding future themes.

Description

Implements a theme system with admin controls and a Christmas theme featuring animated snowflakes.

Backend:

  • model/site-settings.go: SiteSetting key-value model, Theme struct, AvailableThemes() registry
  • dao/site-settings.go: SiteSettingsDao for persistence
  • api/site-settings.go: Theme endpoints (GET /api/theme/active, GET /api/theme/available, PUT /api/theme/active)

Frontend:

  • web/ts/theme-manager.ts: Singleton that fetches active theme on page load, applies effects globally
  • web/assets/css/themes.css: Snowflake animations with prefers-reduced-motion support
  • Admin UI in Maintenance page for theme selection

Adding new themes:

// 1. model/site-settings.go
const ThemeHalloween ThemeID = "halloween"

// In AvailableThemes():
{ID: ThemeHalloween, Name: "Halloween", Description: "Spooky theme", Icon: "fa-ghost"}

// 2. web/ts/theme-manager.ts
class HalloweenTheme implements ThemeEffects { ... }
// Register in themeEffects map

Steps for Testing

Prerequisites:

  • 1 Admin user
  1. Log in as admin
  2. Navigate to Admin → Maintenance
  3. In "Site Theme" section, select "Christmas"
  4. Verify snowflakes appear across all pages
  5. Open in incognito/different browser to confirm theme applies to all users
  6. Select "Default" to disable
