/*
 * Sabyasachi Mishra — author card
 * https://sabya.pm/embed/author-card/
 *
 * One stylesheet, two variants: a pill for a site footer, a fuller box for the
 * author profile under an article. It is written to be dropped into someone
 * else's page, so it takes as little as possible from that page and gives
 * nothing back:
 *
 *   - Every selector is namespaced `.sabyacard`. Nothing is styled globally.
 *   - Type and colour inherit. Text is the host's own colour at reduced
 *     opacity, and the surface, border, and ring are mixed out of that same
 *     `currentColor` — so the card is legible on a white page, a black page,
 *     and a dark footer sitting inside a light page, without being told which
 *     it is. No `prefers-color-scheme` guess is involved. The one literal
 *     colour is the accent on the portrait, which is decorative.
 *   - It reflows by wrapping, not by media query, so it is correct in a
 *     narrow sidebar on a wide screen as well as on a phone.
 *   - Every token below is a custom property. Override any of them on
 *     `.sabyacard` to fit a particular product.
 *
 * Each mixed colour is declared twice: a neutral grey first, then the
 * `color-mix()` value. A browser too old for `color-mix()` keeps the grey,
 * which is deliberately mid-scale and so reads on either extreme.
