One light theme, set entirely in public/css/variables.css: the game's ink
(#1A1722), a violet accent, crown gold, soft surfaces and shadows, Rubik
self-hosted. The sidebar is the game's night ink and re-scopes the text
tokens, so every nav rule works unchanged. The crown and the العب wordmark
replace the "E" mark in the sidebar and on the sign-in page; the dashboard
opens on the four games with today's matches.

- The page grid reserved a sidebar column beside the fixed sidebar, leaving
  an empty band on the far side in RTL; content is now centred in the space
  beside the sidebar.
- The dark/light toggle, the manager-palette tab (and its routes) and the
  stored colour overrides are gone: one designed theme, nothing to drift.
  The per-browser preferences stay; an accent someone picked still applies,
  the old blue default does not.
- Old blue rgba() values now use --accent-rgb; Google Fonts are no longer
  loaded.
