/*
 * SAFIR — the public site and the customer area, in the look of the BRF
 * Solutions site: navy, a yellow accent, tight large headings, rounded cards.
 *
 * One stylesheet for both, served as-is so the static landing pages generated
 * at build time and the Vue application share it. No web font file and no
 * third-party request: Inter when the machine has it, the system face
 * otherwise, and the page is readable before anything else loads.
