/*
  Дистанційна школа Акцент — components.css
  Site-wide reusable UI: buttons, header/nav, checklist, contact form, footer, floating phone.
  Loaded on every page (inner pages + index.html). The header here is the SINGLE source of
  truth — index.html no longer carries its own inline copy. v3.0 — 2026 CSS split.
  Requires base.css (CSS variables).
