/* ==========================================================================
   Salafi Lessons display: the timetable page and the homepage blocks.
   The face, lines, stone, accent and radius come from the values the theme
   publishes (--scm-*, the app's D-344 (16)), so a theme change carries
   through. Each falls back to the token copied from Salafi Prayer Times, so a
   site without them looks as before; the compositions are Lessons' own
   (SL-D-091). Scoped to .sld, never :root. Dark is opt-in per block
   (theme="dark"). Every layout change is a container query on the block, so
   it fits the column it sits in.
