/*
  Дистанційна школа Акцент — ui.css
  Shared "new design" language (2026 handoff): the reusable section/component classes that
  the redesigned pages had been re-implementing inline or in per-page <style> blocks
  (index's inline styles, osvitni's .op-*, zmi's .zmi-*). Extracted here once so every
  migrated page uses ONE source instead of copy-pasting.

  Load order on a migrated page:  base.css → components.css → ui.css
  (ui.css REPLACES pages.css / home.css; it depends on base.css variables + components.css chrome).

  Truly page-unique bits (e.g. osvitni's levels table, vartist's pricing grid) still live in a
  small page-scoped <style> block, exactly like vartist/video do today.
