resolves #4991

What is in this change?

Untitled.2.mov

Refactors the theme system from two options (Default/Light) to three: System, Light, and Dark.

  • System — follows the OS preference and reacts live to changes (e.g. macOS auto dark mode)
  • Light — forces light mode
  • Dark — forces dark mode

Previously, OS preference was only checked once on first load and then locked to localStorage. Now "System" mode continuously listens via matchMedia for OS-level changes.

Also fixes LogoContext to check the resolved data-theme attribute instead of comparing raw localStorage values, which broke logo colors after the rename from "default" to "dark".

Legacy "default" values in localStorage are automatically migrated to "dark".

Additional Information

Only two files changed — useTheme.js and LogoContext.jsx. No CSS, tailwind config, or component changes needed since ThemePreference already renders dynamically from availableThemes and the CSS variable system ([data-theme="light"] override on :root) works with any non-"light" data-theme value.

Developer Validations

  • I ran yarn lint from the root of the repo & committed changes
  • Relevant documentation has been updated
  • I have tested my code functionality
  • Docker build succeeds locally
