/*
 * Styles for crowcorelabs.com.
 *
 * Charcoal and gold: crows, and the shiny things they collect. One accent, system fonts, no build
 * step and nothing fetched from anywhere. The page is a paragraph and a list of links, and it should
 * render instantly, offline, in any browser, in either colour scheme.
 *
 * Contrast: the light-mode accent is a deliberately dark gold (#7a5c0e, about 5.6:1 on this ground)
 * because it is link text and normal-size text needs 4.5:1 for WCAG AA. The brighter gold that reads
 * as "gold" (#e0b53a) only appears in dark mode, where it measures around 9.8:1 on #131316.
