/* Self-hosted webfonts - Inter (body) and JetBrains Mono (code).
 *
 * IDENTICAL IN ALL FOUR MANUALS. If you edit this file, edit the other
 * three: una, una-guide, arp, connect. The font FILES are shared - one copy
 * at the repo root in assets/fonts/, dropped into each build by
 * hooks/self_host_fonts.py - but MkDocs only links stylesheets that live
 * inside a product's own docs_dir, so this sheet has to be duplicated.
 *
 * These replace the Google Fonts <link> that `theme.font` used to emit.
 * Google serves Inter and JetBrains Mono as VARIABLE fonts, and Skia - the
 * renderer behind headless Chrome's --print-to-pdf - cannot embed a named
 * instance of one. It rasterises every glyph to a Type 3 drawing procedure
 * instead, which is why the old PDFs looked right but could not be
 * selected, searched or copied. The files below are static instances: one
 * real weight each.
 *
 * The URLs are RELATIVE, not root-relative. The PDF is rendered from
 * site/<product>/print_page/index.html over file://, where `/fonts/...`
 * would resolve to the filesystem root and quietly load nothing.
 *
 * font-display: block, not swap. On the web the difference is invisible -
 * these are same-origin files of about 23 KB. In the PDF it is the
 * difference between guaranteed Inter and a race with the fallback stack.
