   PIPER, fx-type.css
   The Field Edition, typographic layer only.

   Scope: scale, weight, tracking, optical alignment, and the
   treatment of numerals. The font stack stays Archivo plus
   JetBrains Mono, loaded once in index.html at
   wght@400;600;800;900 for Archivo and wght@500;700 for the
   mono. Every weight referenced below is one of those six
   values on purpose, so nothing here ever falls back through
   the browser's nearest-weight matching by accident.

   Loads after styles.css and overrides its scale. Colour,
   surfaces, shadows and layout are owned elsewhere and are
   never touched here.

   Two numbers on this page describe Piper herself rather than

   in the wild section, falling. They never share a section, so
   the only way a reader can feel that they answer each other is
   if they are built the same way, tabular figures, slashed
   zero, the same 700 mono weight the rest of the page already
   uses for its numbers. Rank between them comes from size only:
   the hero readout is the smaller of the two because it belongs
   to a photograph of one animal, and the 2,500 is sized closer
   to the masthead because it is the fact the whole site exists
   to put in front of that photograph. */

   Archivo components, and labels that live inside the two
   components already set in JetBrains Mono (.receipt, .arcade).
   Splitting on font family instead of forcing one rule onto
   both matters here specifically because only 500 and 700 are
   loaded for the mono face, so a label weight that looks right
   in Archivo can silently resolve to the wrong mono cut. */

   Two different jobs, two different figure styles. Anything

   with lining tabular figures, correct for a column of numbers
   that has to line up. Numbers that turn up inside a sentence,
   a date, a weight, a population count, read instead as part of
   the sentence: proportional, text-height figures rather than
   full-caps-height digits interrupting the line. Where the font
   has no oldstyle glyphs this simply falls back to its default
   figures, so the declaration is free to be correct everywhere
   even on the copy that has no digits in it yet. */
