   HTMLToolz — free tools (Prism area sheet)
   Loaded by views/v2/tools/index.php and views/v2/tools/tool.php after ui.css.
   Two scopes:
   · tl-*      page chrome for the hub (/tools) and each tool page
   · .tool-app the tool UIs that assets/js/tools.js renders into #tool-root.
               Their hook classes (tool-toolbar, out-box, hv-*…) are wired
               into the JS, so they keep their names and get a Prism skin here.
   Tokens and tones only — see docs/design/HTMLTOOLZ_DESIGN_SYSTEM.md.
