/* ==========================================================================
   Pelican Island Ride - UI stylesheet
   "提鹅鹏 · 单车环岛"  cinematic minimal DOM/CSS interface.

   Design language: cream paper, ink, teal and poppy. Hairline rules, wide
   letter-spacing, tabular numerals, serif display type for Chinese and a
   quiet humanist sans for micro labels. No images, no web fonts, no network.
   Everything is driven by the classes that src/ui/hud.js and src/ui/menus.js
   toggle, e.g. `.is-on`, `.is-visible`, `.is-active`, `.is-photo`.
