/*
 * Folio site webfonts — self-hosted.
 *
 * WHAT WAS WRONG. The site named Inter, Heebo, Assistant and IBM Plex Sans
 * Arabic across its stylesheets, and loaded them on three pages. index.html,
 * folio.html and og-image.html linked a Google Fonts stylesheet; the legal
 * documents (privacy, terms, accessibility, atlas), the answers pages and the
 * 404 page linked no webfont at all. On those nine pages every "Inter" and
 * "Heebo" was a name nothing could resolve, so each script fell through to
 * whatever the reader's machine happened to own — measured on 2026-08-10 with
 * CDP CSS.getPlatformFontsForNode against /privacy.html: every Hebrew run came
 * back `.SF Hebrew`, isCustomFont:false. That is a different typeface on every
 * reader's screen, and on a machine whose Hebrew fallback is a serif it is a
 * privacy policy set in a stock serif. That is the bug the owner photographed.
 *
 * Frank Ruhl Libre is new here. The site had no reading face at all; this is
 * the app's (src/main/doc_type.ts), brought over for the same three documents.
 *
 * WHAT THIS FILE DOES. It makes those names real, from this origin, on every
 * public page. No CDN and no external request: the site is Workers Static
 * Assets and the product's own ethos is that rendering the UI must not depend
 * on a third party answering. The CSP already allows exactly this
 * (`font-src 'self'`) — and now that nothing on the site still asks Google
 * for anything, `_headers` was tightened to match it: `font-src` dropped
 * fonts.gstatic.com and `style-src` dropped fonts.googleapis.com, since a CSP
 * allowance for a connection nothing makes is just unused attack surface.
 *
 * THE BINARIES are the app's, byte for byte, for four of the six families —
 * Frank Ruhl Libre, Heebo, Inter, Rubik — the files the desktop renderer
 * ships from src/renderer/src/assets/fonts, verified by sha256 when they
 * were copied. Reusing them rather than re-fetching means the site and the
 * app cannot drift into two different cuts of the same typeface, and it
 * inherits that directory's provenance and licence record.
 *
 * ASSISTANT AND IBM PLEX SANS ARABIC have no app copy to reuse — the desktop
 * app never bundled either family, so the site is their only home. They were
 * the reason index.html, folio.html and og-image.html still linked the
 * Google Fonts CDN after the round above: those two names lived nowhere
 * else. Measured before touching anything, CDN still reachable (CDP
 * CSS.getPlatformFontsForNode, 2026-08-10): Assistant is the DEFAULT BODY
 * face on index.html's Hebrew and English copy — every paragraph, not a
 * heading, since headings ask for Heebo first and Heebo already resolved —
 * and IBM Plex Sans Arabic is the whole-body face for both pages' Arabic
 * mode. og-image.html turned out to use neither: its own CDN link requested
 * only Heebo and Inter, already self-hosted below, so that page's CDN link
 * was dead weight from the day this file was first written; its fix is
 * simply linking this sheet instead of carrying its own. Both other families
 * are genuinely used where they were still requested, so both are
 * self-hosted here rather than dropped — verified after the change against
 * the same elements, same CDP call, same resolved family, isCustomFont:true.
 *
 * Fetched the same documented way this file's original six binaries were
 * (see src/renderer/src/assets/fonts/fonts.css's own regeneration recipe:
 * curl the CSS2 endpoint with a woff2-capable UA, keep the hebrew/latin/
 * arabic blocks, download the gstatic URLs), and not re-subset by this repo.
 * Licence verified against the google/fonts GitHub repository's own OFL.txt
 * for each family: both OFL 1.1, byte-identical licence text to what already
 * sits below, confirmed by direct comparison rather than assumed from the
 * family's reputation. Assistant's OFL carries a Reserved Font Name for a
 * component it incorporates ('Source', from Source Sans Pro); IBM Plex Sans
 * Arabic reserves its own family name ('Plex'). Neither restriction is
 * triggered by shipping the fonts unmodified under their published names,
 * which is all this file does. resources/legal/NOTICES.txt now carries both
 * copyright blocks and says plainly which two families are site-only.
 *
 * Only the subsets the site actually sets travel here: hebrew and latin for
 * the reading and chrome families (Frank Ruhl Libre, Heebo, Inter, Assistant
 * — Inter is latin-only in practice, the site never sets Hebrew text in it),
 * arabic for the two Arabic-script families (Rubik, IBM Plex Sans Arabic).
 * Everything Google offers beyond he/ar/en — latin-ext, cyrillic, greek,
 * vietnamese — is left behind, which is most of what a full family costs.
 *
 * Total cost: 354,392 bytes across twelve files, cached immutable
 * (_headers). No single visit pays for all of them — measured with the
 * network panel, not assumed from file sizes: a Hebrew-default visit to
 * index.html fetches four (Heebo and Assistant, hebrew and latin each),
 * 71,540 bytes; the same page loaded straight into Arabic fetches ten
 * (Heebo-latin, Assistant hebrew and latin, and IBM Plex Sans Arabic across
 * the weights that page's Arabic content actually asks for), 220,600 bytes;
 * loaded straight into English it fetches three (Heebo-latin, Assistant
 * hebrew and latin), 59,540 bytes.
 *
 * ONE BLOCK PER FAMILY AND SUBSET, with a weight RANGE — for the five
 * families that are variable fonts. Each serves every weight the site asks
 * for as a REAL instance instead of a synthesised bold. The ranges below are
 * measured, not assumed: each file was loaded in Chromium and its glyph
 * advance sampled at wght 100..900 through font-variation-settings, which
 * moves only on a real axis. Frank Ruhl Libre and Rubik stopped changing at
 * or below 300; Heebo and Inter answered at every step; Assistant stopped
 * changing at exactly 200 and exactly 800, matching its own declared Google
 * Fonts axis to the unit. Hence 300-900, 100-900, and 200-800.
 *
 * IBM PLEX SANS ARABIC IS THE EXCEPTION. It has no registered variable axis
 * on Google Fonts — confirmed against its own METADATA.pb (no `axes` block)
 * and by the CSS2 endpoint flatly rejecting a wght range request for it,
 * HTTP 400 "Font family not found". It ships here as four discrete static
 * weights instead of one ranged file: 400/500/600/700, the same four the CDN
 * link this replaces was already requesting, and the only four CDP found
 * actually rendering across the two pages that use it.
 *
 * (The app's own fonts.css declares its four shared files as discrete
 * 400/500/600 blocks, because 400/500/600 is the weight set the app UI uses.
 * The site's home page asks Heebo for 800, so the range form is the one that
 * keeps every site weight honest. The two forms were checked against each
 * other on the Arabic: the range declaration and a discrete 400 declaration
 * of the same binary set the same string to the same 1252.484px, so the
 * range really does instance at 400. Worth knowing because CDP reports the
 * resolved face as "Rubik Light" or "Assistant ExtraLight" either way — that
 * is the file's default named instance showing through, not the weight
 * actually being rendered.)
 *
 * The unicode-ranges for the four app-shared families are copied verbatim
 * from src/renderer/src/assets/fonts/fonts.css, which took them verbatim
 * from Google, so the two declarations of the same binary cannot disagree
 * about which codepoints each file actually carries. Assistant and IBM Plex
 * Sans Arabic have no app-side declaration to check against, so their ranges
 * are copied verbatim from Google's own CSS2 response instead — same source,
 * same method, just fetched directly since there was no app copy on hand.
