/* Light theme: real light-UI values (near-white bg, subtle gray tiers, dark
   text), not a naive invert. Same brand accent + one hue per meaning, tuned
   for WCAG AA contrast on light surfaces.
   The "system" choice never reaches this stylesheet as its own state: the
   inline head script (index.html) and app.js resolve prefers-color-scheme to
   an actual "light"/"dark" value and set that as data-theme, re-resolving
   live if the OS preference changes while "system" is selected. That keeps
   the theme's colors defined in exactly one place each, instead of
   duplicating this whole block inside a @media query. */
