/*
 * Type scale (a rule of the product line) and the two families (a decision of the product kit).
 *
 * The scale, weights and line heights below are NOT changed per project: they are what
 * core.md §17 fixes for every product of the line. The families are the old kinvoice.app's
 * (project_files/ui/product-kit.md §3): the system UI stack for text and Noto Serif for headings,
 * the same serif the invoices use. The Noto files are self-hosted (nothing is requested from
 * outside the page — Content-Security-Policy; fonts/README.md): three serif families, one WOFF2
 * file per family and weight, each `unicode-range` the file's own charset as fc-query reads it, so
 * the browser fetches a script face only when a glyph of it is on the page. A document in Armenian
 * or Georgian puts its script family first (--font-display-hy, --font-display-ka; the sheet's
 * language class): the same names Dompdf registers for the TTF files (KINV-19). The sans themes
 * (KINV-137) take Noto Sans the same way: three more families, --font-doc-sans{,-hy,-ka}. The latin
 * files carry U+2212 and U+00A0 (core.md §3).
 *
 * The one extra face is the founder's signature in the public footer: Caveat Medium, the file
 * kador.dev itself serves (owner, 23.10.2026; fonts/README.md, licence OFL.txt). It carries
 * the Latin letters only, which is all the name «Denis Kuzmichev» needs.
