   ⚠️ NEW (Portfolio Demos)

   WHY THIS FILE EXISTS
   The four concept demos under /demos/ are deliberately four *different*
   websites, not one template themed four ways: each has its own type scale,
   layout system, palette and section rhythm, and none of them imports
   another's stylesheet. The only thing they legitimately share is the Apex
   attribution chrome — the strip that tells a visitor "this is a concept
   demo of a fictional business, and Apex built it" — because that message
   must read identically on all four and must never drift.

   So this file styles the CHROME AROUND a demo, never the demo itself. It
   deliberately contains no typography scale, no layout grid, no component
   any demo page composes with. If a rule here would change how the fictional
   business's own site looks, it belongs in that site's own stylesheet.

   Each demo supplies the five custom properties below on :root so the strip
   sits inside its host palette instead of fighting it.

   No inline <style>/<script> anywhere under /demos/ (D-003), so that route's
   CSP needs no hashes and these files can be edited freely.
