A deliberately-unfinished second adapter that consumes the same ir/ and honours
the same adapters/ADAPTER_CONTRACT.md (token full-gen + write-once stubs + drift
roll-up shape + exit codes), with zero changes to ir/. Every IR component is
'new' for a fresh stack → 10 class stubs + tokens.css (80 props). Not a usable
plain-CSS kit — the deliverable is confidence the boundary holds so the
architecture can be lifted into a coulomb-level tool later. make adapt-plain-css.
