/* ==========================================================================
   geodika.id — public site stylesheet
   Source of truth: design-system/geodika/MASTER.md (+ pages/*.md overrides).
   Admin pages keep using style.css (see base.html).

   Deliberate deviations from MASTER (stricter accessibility standard):
   - cursor:pointer and hover lift only on elements that are actually links/buttons
   - no `outline: none`; every interactive element gets a 3px :focus-visible ring
   - transitions list explicit properties instead of `all`
   - cards are white (--color-card) on the #F8FAFC page so they read as surfaces
