/* Perfect Boyfriend. Look borrowed from Fitness Tracker ("match my apps"):
   same dark tokens, gold accent, bottom tab bar on a phone, sidebar on a
   laptop, no bordered cards (hairlines and spacing instead), the window never
   scrolls (only the pane inside a screen does).
   This file: tokens, shell (nav, top bar, sub-tabs) and shared pieces.
   Each screen's own styles live in css/<screen>.css. */
