/* Bedside: the look set in Shareable-Reading-App-Design.md (a warm paperback with large-print sizes).
   Rules that matter here: nothing under 18px, every control at least 48px (main buttons 56px), only the
   colours of design section 3, sentence case, no italics, no light weights.
   Every size is in rem, with the root at 125% (so 1rem is 20px at the standard text size). 18px is 0.9rem,
   48px is 2.4rem, 56px is 2.8rem. The Text size setting changes the root: 137.5% (Large), 150% (Largest). */
