/* Tekfile demo portal — taste-skill app run, style "framed-sheet" (seed 1682957941), brand palette and type kept
   from site/assets/site.css (one ink, one petrol accent, IBM Plex Sans, Noto Sans Arabic, citation chips).
   Shell: one tinted L-frame (top bar 48px + sidebar 240px, no rule between them); the work sits on a white
   sheet inset 8px from the window's right and bottom edges, 1px edge, 16px corners, no shadow.
   Grid arithmetic at 1440: sheet 1440 − 240 − 8 = 1192; minus 2 × 24 padding = 1144;
   12 columns, gap 16: 12 × 80.67 + 11 × 16 = 1144; viewer 8 cols = 757.3, side column 4 cols = 370.7,
   757.3 + 16 + 370.7 = 1144. Radii: 16 (sheet), 8 (cards, viewer), 6 (controls). */
