/* ===========================================================================
   The typefaces, self-hosted.

   The visual system in styles.css has always asked for Archivo, Public Sans
   and IBM Plex Mono. Nothing ever loaded them, so every one of them fell back
   to system-ui: the display/body distinction collapsed, `font-stretch` did
   nothing (system fonts have no width axis), and the slashed zero that keeps a
   column of figures readable never appeared. The design was written down but
   not shipped.

   Linked by both documents -- index.html and app/index.html -- rather than
   imported by the application stylesheet, because the landing page never
   loads that stylesheet and still has to be set in the right faces.

   Self-hosted rather than fetched from a CDN, because public/_headers keeps
   font-src at 'self' and that is worth more than the bytes. All three are
   SIL Open Font License 1.1, which permits this.

   Files are the `latin` and `latin-ext` subsets from Google Fonts. The
   unicode-range on each is what makes latin-ext free: a browser fetches it
   only if the page actually contains a character in that range, so a US
   tenancy pays for latin alone.

/* --- Archivo: headings, eyebrows -----------------------------------------
   Variable on both weight and width. The width axis is the point -- the
   mastheads and section labels are set slightly expanded, which is what makes
   them read as ledger rulings rather than as ordinary bold text. */
