   Kibermokymai — public site design system (2026 redesign)
   The binding brief is docs/DESIGN.md. Desktop borrows hostinger.lt's
   confidence (bright violet, bold display headings, rounded cards, tabbed
   showcase, dark stats band); mobile borrows senukai.lt's thumb-first
   discipline (compact sticky header, chip rows, full-width targets, sticky
   bottom bar). Everything sits on an 8px grid. Pages compose these classes
   and never invent colours or sizes.
