/*
 * corgos-id-button.css — the standard "Sign in with Corgos ID" button (the Corgos ID kit, v1;
 * canonical in auth.git kit/, byte-copied beside corgos-id-mark.svg, never edited in an app).
 *
 * Self-contained: no Cirrus, no font to load, no variable from the page — it looks the same on any
 * page. Light by default; add corgos-id-button--night on a dark ground. A 44px touch target, a focus
 * ring that shows on any ground, the mark drawn from corgos-id-mark.svg beside this file.
 *
 *   <a class="corgos-id-button" href="/auth/login">Sign in with Corgos ID</a>
 *   <button class="corgos-id-button corgos-id-button--night" type="submit">Prijavite se Corgos ID-om</button>
 *
 * Contrast (WCAG 2.2): text 17:1 on either ground; the edge 4.0:1 on white and 4.3:1 on the night
 * ground; the focus ring 4.5:1 on white and 8.2:1 on the night ground.
