/* ==========================================================================
   BLUE REALM — THEME
   ==========================================================================
   ALL COLORS LIVE IN THIS ONE :root BLOCK. To change the accent color,
   background darkness, or contrast anywhere in the app, edit the values
   here — nothing else in any page needs to change.

   Text colors (--ink, --ink-muted, --ink-faint) are contrast-verified
   against WCAG AA/AAA. If you change them, re-check contrast before
   shipping — see the note above each one.
