/*
 * Article body: the one stylesheet for every place an article is read.
 *
 * Published pages (blogs /s/, magazines /m/, Discover /a/) inline it through
 * htmlgen/css.py; the editor and its preview import it from
 * src/assets/article-typography.css. Both renderers (mistune on the server,
 * marked in the app) emit the markup it styles, so what a writer previews is
 * what readers get.
 *
 * Scale: Apple's text styles at the default size (Body 17 pt) on a modular
 * scale of 1.2. Title 3 is 1.2em (20 pt), Title 1 about 1.73em (28 pt),
 * Footnote about 0.83em (13 to 14 pt) and Caption about 0.75em (12 pt).
 * Leading is opened up for long reading.
 *
 * Cascade: size, leading and colour sit on the container and are inherited,
 * so secondary text (footnotes, tables) scales from one place. Element
 * defaults are wrapped in :where() and weigh one class: a component inside
 * the article (a mention, a player, an interview) styles itself with its own
 * class and wins without overrides or !important.
 *
 * Colours come from the theme tokens (theme.py). --theme-link is the accent
 * adjusted until it reads at 4.5:1 on the page background.

/* ── Lead card ───────────────────────────────────────────────────────────
   The lead article of a magazine/wiki section. Same card, same frame, bigger
   type: the hierarchy is scale, not a separate layout.

   It sits side by side when there's room and stacks when there isn't — and it
   decides that from *its own* width, not the viewport's, because the same card
   renders in a 56rem page column and in a wiki pane narrowed by the sidebar. A
   full-width lead picture would be ~500px tall on a section index and push the
   actual index below the fold; halved, the artwork still leads without eating
   the screen. */
