/**
 * Error pages (404, 500, 503, …) — compact, quiet, no shadows.
 *
 * Standalone on purpose: errors/base_error.html loads only the token files,
 * main.css and this sheet, so an error page still renders when the rest of the
 * site is degraded. It follows the public brand system (ifinsta blue, Plus
 * Jakarta headings, pill buttons, hairlines instead of shadows) through the
 * --ifinsta-mk-* tokens, and colours by severity: blue by default, amber for
 * 403/429, red for 5xx.
