   Trailhead Bicycle Co - hand-authored, token-driven design system
   No framework, no build step, no preprocessor. This is showcase build 3 of
   4 - palette, type, radius, logo, and page structure were all redecided
   from scratch rather than reused from builds 1-2. See README.md "Design
   notes" and Builder Man/memory/showcase-builds-batch.md.
   Both colour schemes verified programmatically for WCAG AA contrast - see
