   Reads exclusively from the tokens in themes.css. No hard-coded colours.
   Bootstrap supplies the base reset (Reboot) and the JS-component CSS
   (modal, offcanvas, toast, dropdown, tooltip, collapse). Tailwind supplies
   layout utilities (Preflight disabled). This file owns the visual identity.
