/* =====================================================================
   Tiltless — Flat (the default card style since November 2026)
   Calm, solid surfaces: no glass, no glow, no gradient edges or sheens,
   no boxes inside boxes, one accent used sparingly.
   Everything here is scoped to html[data-glass="flat"], so the Frosted /
   Clear glass styles (Settings → Card style) keep working as before.
   Loaded last, after every other stylesheet.
