/* ============================================================================
   This file loads AFTER theme.css (see index.html) and is what actually
   governs the pupil UI -- but only for the properties it redefines. A
   component can therefore take its layout from theme.css and its type scale
   from here, and each file looks self-consistent while the combination is
   not. That is not hypothetical: .parent-head is laid out as a no-wrap flex
   row in theme.css, sized when its heading was 22px, and this file later
   raised that heading to 1.75rem -- which pushed the sign-out control off
   the right edge on a long school name.

   So: before changing a rule here, check whether theme.css also styles that
   selector, and vice versa. `node tools/css-overlap.mjs` lists every
   selector defined in both files.
