   IPTV Checker — Premium SaaS diagnostic page
   Location: assets/css/iptv-checker.css

   Loaded LAST so it refines the page's existing (mostly token-based)
   inline styles + tool.css without edits. Scoped to `.tool-page` and
   `.iptvc-*` so nothing else is affected. Purely presentational — every
   ID/class the checker JS uses (.method-tab[data-method], #panel-*,
   #checkBtn, #resultBody, download buttons …) keeps its behavior.
   Credentials login, M3U URL checks, file uploads, Xtream lookups,
   results and downloads are untouched.
   ============================================================ */

     defined globally — so it fell back to light grey in BOTH themes and
     broke dark mode on tabs / upload zone / download buttons / file info /
     progress tracks. Map it to the theme-aware token to fix all at once. */
