/* Patrick.ai storefront — the shared stylesheet.

   BRUTALIST (owner, 2026-10: "much more brutalistic, simple, and modern —
   not rounded like it is today"). Square corners everywhere, hard 2px rules
   instead of shadows and blur, flat black and white, and ONE colour — a
   signal yellow — for the one thing to press. Type does the work: a heavy
   grotesk set large and tight for headlines, a monospace for numbers,
   labels and the nav. Every page in this workspace inherits it; the
   landing page adds static/css/landing.css on top.

   The token NAMES (--sky-*, --star, --gold, ...) are kept from the earlier
   night-sky design so nothing that reads them needs to change; their
   values are now black, white and greys. `--r*` are 0: a radius anywhere
   in this workspace is a bug.

   No web fonts and nothing fetched from anywhere else (businesses/AGENTS.md,
   "The stack"): both faces are system stacks. */
