/* Street Banker public header.

 * Hand-written rather than Tailwind classes: the build is checked in and
 * frozen (tests/test_stylesheet.py fails on any arbitrary value the build
 * has not seen), and this header needs exact values - an 86px bar, a 42px
 * CTA, a 2px radius, a scroll transition under 200ms. Tokens live at the
 * top so nothing downstream repeats a raw hex.
