/* Typography.
 *
 * mandoc.css sets `body { font-family: Helvetica,Arial,sans-serif }` and
 * `pre { font-family: inherit }`.  Prose is switched to Times New Roman here;
 * literal blocks, code and the monospaced semantic classes are pinned to a
 * real monospace stack so ASCII diagrams, unit files and the randomart keep
 * their column alignment (a proportional font would destroy them).
 *
 * This file is linked after mandoc.css, so equal-specificity rules win here
 * and upstream mandoc.css can be updated without losing these overrides. */

/* Dark mode, always — with a softer palette than mandoc.css ships.
 *
 * mandoc.css only flips `--bg`/`--fg` to #1E1F21/#EEEFF1 inside
 * `@media (prefers-color-scheme: dark)`, and near-white on near-black is
 * the worst case for long serif runs: Times New Roman hairlines bloom and
 * the text glares.  The foreground is therefore a muted warm grey (~9:1
 * contrast instead of ~17:1) and the links are desaturated instead of the
 * pastel #BAD7FF/#F6BAFF.  `:root` outranks the bare `html` selector
 * mandoc uses, so this wins in both schemes; the link colours have to be
 * restated because that media block recolours them too. */
