/* kazakhtili.com — modern minimalist light
 *
 * Design rules:
 * - One typeface: Inter (good Cyrillic). Display sizes get tighter tracking.
 * - Hairline borders only (1px). No drop shadows. Subtle hover lift.
 * - Single accent: indigo. Lesson tags use a per-lesson color.
 * - 8pt grid. clamp() for responsive type. Generous whitespace.
