/*
  Design tokens carried over from design/medbook-ui-mockup.html. One real difference: the mockup
  loads Fraunces/JetBrains Mono/Inter from Google Fonts over an @import — this app's CSP only
  allows 'self' for style-src/font-src (no external CDN, matching every other project in this
  org), so that @import would simply be blocked. Using system font stacks that approximate the
  same character (serif headings, monospace labels) instead of embedding a fake/broken @import.
  Self-hosting the real Fraunces/JetBrains Mono/Inter Tight files (same `make fonts` pattern
  digi-soft-app/scholarsite already use) is the natural follow-up, not done in this pass — no
  internet fetch of font binaries was available here.
