/* Абашево — the interface.
 *
 * The palette is sampled from the wordmark rather than chosen: oxblood #623830
 * on parchment #F2E1BA. Contrast measured, not assumed — ink on page is 9.16:1
 * and ink on parchment 7.64:1, both AAA.
 *
 * Parchment is the header band only. A full page of it behind dense Russian
 * prose is tiring and leaves nothing lighter to sit underneath, so the page is
 * the same hue lightened.
 *
 * Typefaces are self-hosted: this site serves an unpublished manuscript and
 * should not announce every page view to a font CDN, and the box should not
 * need outbound network access to render. Both have complete Cyrillic, which
 * eliminates most alternatives — the whole interface is Russian.
