/* ==========================================================================
   Appointments — public pages, layout utilities (c.4.2.26, iteration 3)
   --------------------------------------------------------------------------
   The public booking pages used to load Tailwind's play CDN: an external
   script on a public page, and CSS generated at runtime, i.e. a flash of
   unstyled content on every open. This sheet is the handful of layout
   utilities those three pages actually use, with Tailwind's names so the
   markup stayed the same, plus the small reset the markup relies on.

   Nothing about COLOUR lives here — colour is tokens in
   appointments_public.css. Add a utility here only when a view needs it;
   the list is the inventory, not a framework.
