/*
  💬 Help: the help chat's button and panel (web/help.js, DESIGN.md "Phase 8: 💬 Help chat").
  choreboy.css's tokens and components (.chip, .btn, .input), so light and dark follow the device.
  From 760 px wide the panel is a side sheet on the right (the page stays usable beside it); below
  that it's the whole screen. Responsive to 320 px.

  WIRING: web/index.html loads it after work.css: <link rel="stylesheet" href="help.css">.
  (help.js's header has the rest.)
