/* ============================================================================
   QRK.LT — "MODULIS" design system (V2.2, 2026-07-20).
   Vienas principas: QR modulis (kvadratas) yra sistemos kalba.
   Popierius + anglis + viena elektrinė mėlyna. Santūru: plonos linijos,
   erdvė, didžiosios raidės tik akcentui. Tipografika — Space Grotesk +
   Space Mono, savarankiškai talpinama (jokių CDN, veikia neprisijungus).
