/* Metric-matched fallbacks for the three web fonts (audit 2026-10-01, live-walkthrough-3). The fonts come from Google
   with display=swap, so the page first draws in a local font and redraws when the web font lands; Instrument Serif is
   far narrower than Georgia and DM Sans narrower than the system sans, so headings and paragraphs re-wrapped and the
   front page's hero jumped (CLS about 0.42 measured locally at 1440x900, 0.46 in production; Google calls over 0.25 poor).
   Each face below is a local font scaled (size-adjust) to the web font's width and given its ascent and descent, so the
   first draw takes the same room as the final one. The final look is unchanged: the web fonts still come first in every
   stack, and unicode-range is exactly the latin + latin-ext subsets Google serves, so a character none of the web fonts
   has (an arrow, a symbol) still falls through to the system font as before.
   Measured in Chrome 2026-10-01 from the front page's own text (canvas widths, weighted by how much text each weight
   carries; vertical metrics as Blink reads them): DM Sans 400/500 against Arial, 600/700 against Arial Bold, Instrument
   Serif against Georgia, JetBrains Mono against Courier New. Overrides are divided by size-adjust because the browser
   multiplies them by it. Arial, Georgia and Courier New ship with Windows, macOS and iOS; Android has none of them, so
   it gets Roboto and Noto Serif faces measured the same way from Google's web copies of those fonts (not checked on a
   device). A face whose local font is missing is skipped and the next family in the stack is used.
   Linked only where the web fonts are (index.html, directory pages): a page without them must not switch to these. */
