/*
  ChoreBoy's Phase 7b screens (DESIGN.md "Phase 7b"): the 👥 Friends view (web/friends.js, fr-
  classes), the 🔔 bell and notifications panel (web/notifications.js, nt- classes) and sharing one
  task (web/share.js, sh- classes: the editor's "👥 Share" picker and its dialog, the "👥 Celeste,
  Adam" tag and its who-sees list, "From Jared" / "Shared by Jared", the two filters).
  choreboy.css's tokens and components (panel, btn, chip, input, group-head, empty-state, link-btn,
  list-head), and upcoming.css's person colors (hh-c0 … hh-c7 set --hh) and avatar (.hh-av), so
  light and dark follow the device. Phones from 320 px; prefers-reduced-motion respected.

  WIRING: web/index.html loads it after upcoming.css: <link rel="stylesheet" href="social.css">.
