/* Even — shared styles.
 *
 * The design language is the app's: a night ground, one warm accent, cool
 * everything else, and prose that turns serif when Even is speaking to the
 * reader. The page's own signature is the five mood marks, which are the
 * app's geometry rather than an impression of it (tools/make-glyphs.py).
 *
 * Every colour below is Theme.swift's `corridor` token set converted to sRGB
 * hex, so the site and the app cannot drift apart. Two rules come with them:
 *
 *   1. `--dawn` is the warm accent and appears once per section. Twice on one
 *      screen and one of them is wrong. Everything else cool.
 *   2. Figures are monospaced and thin. Every number on this site is a
 *      measurement, and a measurement reads as an instrument, not a score in
 *      a game.

 * wider card leaves a ragged column of dead space beside it, and then the
 * caption underneath has to decide whether to line up with the phone or with
 * the card. Filling the card removes the question: image and caption share
 * one left edge and one right edge.
