Typography analogue of applyColorScheme: derive a whole `--font-size-*`
ladder from one modular ratio + base, optionally fluid (`ratioMax` grows
the scale on wide screens), applied as a managed `:root` block that
overrides the theme authored sizes at runtime.
- buildTypeScale(seed) — pure, in eidos/lib; mirrors build-scheme. Steps
the 8 named sizes (xxs..xxxl) off `md`=base via the ratio; reuses
fluidClamp; composes with `--scaling`.
- ActiveEidos.applyTypeScale(seed, opts) / clearTypeScale() — managed
block written last so it wins over the static sizes.
- exported from $uix/eidos (buildTypeScale, typeScaleDeclarations, types).
`npm run check` 0 errors; buildTypeScale + applyTypeScale tests pass. The
managed-block DOM path is the same mechanism as applyColorScheme; the
/temas/tipografia showcase will dogfood it live.
