/* ==========================================================
   TBB Agenda Grid - frontend styles.
   All custom properties are scoped to .tbb-agenda so this never
   leaks variables into the rest of the theme. Dark mode is a data
   attribute on the same root element, toggled by agenda.js.

   Shape language: intentionally squared-off (4-6px radii), solid
   flat colour blocks, monospace for time/data, and a stripe-left
   card treatment - kept deliberately distinct from soft
   pill/glassmorphism conference-site templates.
