/*
 * css/reading.css · The Long Game — Reading Room styles (.reading-*)
 * Purpose: a formal, editorial treatment for the reading-room shelf (openReadingRoom)
 *   and the focused reader (openReading) in js/app.js. Deliberately more composed and
 *   professional than the rest of the app's warm surfaces: a quiet index of essays and
 *   a comfortable serif reading column. Design tokens only — no user text in any CSS.
 * Related: js/app.js (openReadingRoom / openReading), js/readings.js (content).
