/* satranc.app — the stylesheet (v3 "Aydınlık", 2026-09-15; the owner's canvas, UI/site-redesign).
   The app's light chrome on a calm page: a rail of six words on the left, one column of
   content, 15 px text on the rebuilt pages, 44 px controls, r8 chips · r14 controls ·
   r20 cards, neutral words. Phones: the rail becomes a bottom bar, boards run edge to edge.
   The v2 classes (13 px, panels, three columns) still dress the pages not yet rebuilt
   and leave with them. Type: Bricolage Grotesque for titles, Manrope for text,
   JetBrains Mono for numbers. */
