/* ==========================================================================
   Dans Development: S3 "Dlaždice" (tiles), chosen by danek 2026-09-23.
   One look, no theme switcher. Sky / white / navy tiles, each carrying one
   message and one big picture of real work. Glass: the nav only.
   Self-hosted Onest (variable 400-700). The homepage uses this file alone;
   the generated pages (landing pages, /soukromi, 404) add css/s3-page.css.

   EXPERIMENT SWITCH (2026-09-23): the still sky tiles drift slowly.
   To turn it off, set  --sky-drift: none;  in :root below. That is the
   whole revert; the sky layer itself stays (it also fixes the Kontakt tile).
