/*
 * The Martkos IT site header, reproduced on the tools origin.
 *
 * Built from martkos-it-branding/brand-guidelines.md rather than by copying the live
 * site, because the two disagree: the guide records (2026-08-09) that a white label on
 * Coral is 2.8:1 and fails WCAG AA, that the label must be Navy Dark at 6.3:1, and that
 * "any product still shipping a white label on Coral is non-compliant and should be
 * updated". The main site's .btn-primary is still white. Matching the guide is what
 * keeps every product consistent; matching the site would have copied its one error
 * into three more places.
 *
 * The fonts are self-hosted. The guide imports them from Google, which this origin's
 * CSP (`font-src 'self'`) forbids — and rightly: a page whose entire claim is that it
 * talks to nobody cannot fetch a font from a third party on every load. Both are OFL
 * licensed, so shipping the files is permitted; the latin subsets total ~70 KB and are
 * cached across all three tools, which share this origin.
