/* FileConvert — the /tools directory.

   Layered over stylesheets/theme.css: this file uses the shared components
   (.vhero, .fxtrio, .liftcard, .band, .catchips, .extgrid, .pairlink,
   .minilabel) and only adds what the directory itself needs. It never
   redefines a theme token.

   Every selector is namespaced .tools-* so it cannot collide with form.css,
   pages.css or chrome.css. Colours come from --t-* / --primary-* only, so the
   page follows data-theme="dark|light" without a second ruleset. The one
   exception is inside .vhero, which is a permanently dark surface and where
   literal light-on-dark values are the correct answer.

   The page lists ~950 links: density, alignment and legible hover states
   matter more than decoration. */
