   Tahara — shared app shell
   The single source of truth for the logged-in app (dashboard, calendar,
   cycles, veset kavuah, reminders, settings, billing, support).

   Rules of the road:
   - Do NOT redefine any selector from this file inside a page's <style>.
     Page <style> blocks are for genuinely page-specific layout only.
   - No glow. Solid colours, tight shadows. No gradient-clip text.
   - The whole shell is one flat tone (--bg). Header, sidebar and page body
     all paint the same token so they can never drift apart.
