/*
  The WCAG 2.1 AA floor, lifted whole: contrast-checked color variables for
  both schemes, prefers-reduced-motion, :focus-visible outlines, .sr-only,
  and the tablist styles. Removed: the .appa-chat-* bubble and composer
  rules. Class prefix renamed appa- -> hub-. A skip link was added, since
  the shell has a real nav now.

  --muted is the only knob for secondary text, and its value must hold
  4.5:1 against --panel in both schemes. Do not dim it with opacity.

  The login block was added with the same floor in mind. Its rules:
    - every control clears 44px, because these are school iPads;
    - inputs are 16px or larger, because iOS zooms the page on anything
      smaller the moment a field takes focus;
    - --danger is the error colour and holds 4.5:1 in both schemes, but
      colour is never the only signal: errors also carry role="alert" text;
    - the layout is a single column that works from 320px up, since half the
      parents read this on a phone.
