/* ===== Zvládám – MOTIV (design tokens) =====
   Celý vzhled aplikace vychází z těchto proměnných. Grafický návrh „noční modrá“ (31. 10. 2026):
   tmavě modrý úvod a lišta, světlá stránka, nadpisy Lora, text Figtree, podpis Caveat.
   Rozvržení a součásti jsou ve style.css, ucty.css a uvod.css a používají jen proměnné odsud.
   Barva oblasti (--hlavni) se nastavuje v oblasti/<oblast>/__init__.py.
   Písma jsou uložená v static/pisma (licence SIL OFL) – nenačítají se z cizích serverů. */
