/*
 * The look of blog.krasnerteam.com: same colours, type, header, footer and
 * marker-pen highlight, so a visitor moving between the two sees one brand.
 * The blog's own theme documents these tokens; keep them in step with it.
 *
 * Constraints that shape this file:
 *  - One stylesheet, no @import, nothing from another origin (the CSP allows
 *    only 'self', and the privacy page promises no third-party requests).
 *    The fonts and logo are files on this site, not loaded from the blog.
 *  - No inline styles anywhere in the markup - the CSP forbids them.
 *  - Light only, like the blog. `color-scheme: light` keeps form controls light.
 *  - Mobile first: it works at 320px, and the card only appears when there is room.
