/* reading.css - reading, listening and the word look-up (U track: js/screens/read.js, listen.js, js/study/lookup.js).
   Only what the design system (app.css) does not already have; colours, sizes and space only through its tokens, so
   light and dark follow by themselves. Rules it keeps: 44 px targets; 14 px text at the least; nothing wider than the
   page at 320 px; Japanese in .ja / .ja-lg keeps its fixed ruby line height, so a tapped word, a lit sentence or the
   furigana switch never moves a line; the bar at the foot and the look-up sheet sit above the tab bar and Tomo
   (--tutor-room), and on a wide screen Tomo has her own lane, so nothing here is ever under her. Phone first
   (docs/mobile-plan.md J12 to J15): lists are rows, the player is docked at the foot of a phone's screen, and a
   tapped word opens a bottom sheet of about half the screen (its pitch, kanji and Keep under More). */
