Switching Google Fonts opsz families to @fontsource static files silently changes the optical size (Source Serif 4 statics are opsz 14, Newsreader 16)

Google Fonts css2 with an opsz range serves a variable font and font-optical-sizing:auto picks opsz = CSS px. @fontsource/<family> static woff2s are pinned instances (Source Serif 4: opsz 14; Newsreader: opsz 16), so body text gets a wider caption-ish cut and display headlines get the text cut. Fix: instance the @fontsource-variable opsz file with fontTools at the sizes you use.

Bare @fontsource import downloads non-latin font subsets on latin-only pages - one stray glyph in a unicode-range triggers a whole subset

Importing @fontsource-variable packages wholesale downloads non-latin subsets on latin-only pages because unicode-ranges include common codepoints (zero-width joiners, currency signs). Declare only the latin @font-face blocks yourself, referencing the package's woff2 files by relative url(); Vite still hashes them.
