/* =========================================================================
   SLIM DIET — the website's shared stylesheet.
   -------------------------------------------------------------------------
   One stylesheet for every page on drslimcare.com: the six static pages
   and the blog. The calculator has its own (calculator.css), and so does
   the blog's article typography (blog.css); everything else is here.

   The visual language is the customer app's (app.drslimcare.com): navy for
   the brand and every solid button, teal for focus, selection and accents,
   white cards on a cool off-white page, IBM Plex Sans Arabic for both
   scripts. The colours below are the handoff's tokens, word for word.
   Change a colour here and it changes everywhere; nothing else in the
   site should name a raw hex value except the two data: URIs for the mark.

   Cache: every page links this file as site.css?v=<hash of this file>.
   After editing it, run  php tools/stamp-assets.php  so the pages ask for
   the new version; the check script in CLAUDE.md fails until you do.

   RTL: only logical properties (margin-inline, inset-inline-start, ...).
   Never left/right. Arabic gets no letter-spacing — see the end of file.
