/* ====================================================
   slide-captcha.css — page-specific overrides for the
   Slide Captcha documentation tool page.
   Shared components live in tool-page.css. Only the
   documentation layout below is unique to this page.

   REFACTORING STATUS: Components below can migrate to
   fc-* classes from tool-page.css (see mapping below).
   For now: keeping for backward compatibility with HTML.

   Migration path when updating HTML:
   .sc-card → .fc-doc-card
   .sc-code → .fc-code-block
   .sc-copy → .fc-copy-btn
   .sc-table → .fc-doc-table
   .sc-list → .fc-doc-list
   .sc-feature(s) → .fc-feature(s)
   .sc-note → .fc-highlight
   .sc-download → .fc-file-box
