/* ══════════════════════════════════════════════════════════════════════════
   Clearbay Digital — shared base stylesheet.

   Loaded by every page. Everything in here is used on more than one page:
   the font, the reset, the design tokens, the section vocabulary, the button
   family, the brand lockup and the small footer.

   Page-specific rules stay with their page. The homepage's live in /home.css
   (it has enough of them to be worth its own file); every other page keeps a
   short inline <style> block after this one, so its own rules always win.

   Adding a page? Link this file, set --container-max, and write only what is
   genuinely new.
