/* blyg — one hand-written stylesheet, no build step, no web fonts.
 *
 * The design idea (session 19): **the editorial apparatus is the design.**
 * What distinguishes a blyg from a blog is that every item wears its own
 * revision history in public — "v2 · pinned: v1, v2", Created/Most-recent,
 * the provenance line under a transcluded quote, the endcap where a withdrawn
 * item used to be. All of that used to render as one undifferentiated grey
 * murmur (0.85rem, opacity 0.7). Here it gets its own typeface and its own
 * colour, consistently, so a reader can learn to read it; the prose gets a
 * serif and is otherwise left alone.
 *
 * The colour that carries it is an editor's blue pencil. To "blue-pencil" a
 * manuscript is to edit it — the same copy-desk world [TK] comes from — so
 * every editorial mark on the page is blue: pins, provenance, the rule beside
 * a transclusion, the kind marker. Prose is ink; nothing else competes.
 *
 * NO WEB FONTS, deliberately. A reference client for a decentralised medium
 * should not make every reader's page load phone a third-party font host;
 * self-hosted static files that depend on someone else's CDN are not really
 * self-hosted. System stacks only.
