/* INDOOR SCIENCES / LAB STUDY
   One visual system: 4 / 8 / 12 / 16 / 24 / 32 / 48 / 64 / 96 spacing.
   Archivo 300 reading + display; 400 labels + controls; Archivo data (Fragment Mono until 0.48.0).
   1 Oct 2026 (p28, the approved serif/sans pairing, brief section 3): data, indices and codes are
   Archivo too, so the site is two families, Archivo and Fraunces. The --mono token keeps its name
   (some 60 rules use it) and now names Archivo; numerals in those rules take tabular figures
   (content.css 21), so columns of figures still align.
   2 Oct 2026 (0.49.0, brief section 7): Archivo's fallback is Arial, which sets wider (Archivo
   300 is .966 of Arial's width on the site's own text, 400 .992; tmp/is-p29-20261002/probes/
   width-ratio.js), so when the web fonts arrive late, text above the reader wraps into fewer lines
   and the page above shortens by up to about 200px on a phone: a layout shift of about .1 with
   Methodology or the founder quotation on screen (probes/late-font.js). 'Archivo Fallback' is
   Arial (or Liberation Sans, its metric twin) scaled to Archivo's width at each weight, with
   Archivo's own vertical metrics (ascent .878, descent .210, no line gap), so the fallback wraps
   as Archivo will. It only acts while Archivo is loading; once it has loaded, nothing drawn changes.
   Where neither Arial nor Liberation Sans exists (Android), the face is skipped and the stack
   behaves as before. Each face covers exactly the characters Archivo's own three subsets cover
   (fonts.css), so characters outside them (U+2082 and U+2083, U+0394, U+2192, U+2264 and U+2265)
   keep the system fallback they had and are not drawn by a scaled Arial.
