web: move the type scale onto typography-* utilities
the scale lived in @theme as --text-heading-*, --text-paragraph-* and
--text-monospace-*, so it generated text-heading-3, text-paragraph-small and so
on. tailwind-merge classes anything shaped like that as a colour, so inside a
tv() whose variants set text colours it dropped the size as soon as a colour
followed — which, in those definitions, is always. $lib/tv.ts existed only to
re-register the twelve names as font sizes, and every tv() in the app had to
import from there rather than from tailwind-variants to pick that up.
naming them typography-* sidesteps the collision instead of patching it: the
classes match no tailwind-merge group at all, so nothing can read them as
colours and the shim is gone. they're @utility blocks rather than theme tokens
now, since --text-* is precisely the namespace that spells its utilities text-*.
font-size comes first in each block on purpose. tailwind sorts a custom utility
into the bucket of its first declared property, which keeps typography-* ahead
of every font-weight, leading-* and tracking-* utility in the sheet, so the call
sites pairing typography-heading-4 with leading-8 font-normal still resolve the
way they did.
this does give up size-against-size merging: two typography-* classes in one
string no longer collapse, so a size passed in through class= sits next to the
component's own and the stylesheet order picks the winner. nothing does that
today — Typography takes a variant prop for it — and one classGroups entry
brings the merging back if it ever comes up.
