   Tools — the hub and the pages under /tools.

   Built on the tokens already shipped by css/secilen.css (--c-*, --fs-*,
   --radius*, --gap-*, --shadow-*, .wrap) so a tool page reads as part of the
   site without restating the palette. css/hair-analysis.css stays separate:
   it owns the upload and report components that only that page has.

   Loaded after the shared sheets, so it wins where it overlaps.
