/*
  Spell Beasts for Schools: P1's screens (docs/TEACHER-UX.md sections 5.3 and 5.5-5.9): This week
  (wk-), the challenges list and a challenge (ch-), New challenge (nc-) and the word sheet (wd-).

  Built on the shell's pieces in teach.css (t-sheet, t-btn, t-fig, t-dt, t-chip, t-bar, t-mk,
  t-egg, charts): this file only lays out P1's own screens and never restyles a t- class.
  The Today card carries the page's only yolk (primary) button; its left edge is yolk too.

  What this must never do: carry meaning in colour alone (every bar segment has its words,
  every egg its label), hide focus, or let a page scroll sideways at 390px (only a table or
  a grid inside its own box may).
