The rectification session rendered its own textarea (no length ceiling,
no count), its own rAF scroll follow with a sticky-scroll helper, and its
own jump chip styled differently from the main chat's inline Tailwind
button, while the main chat re-ran scrollTo on every streamed token and
added a smooth scroll on settle. ChatComposer now accepts a controlled
value so the rectification surface reuses it without touching the main
draft store; useConversationScrollAnchor owns the follow through a
ResizeObserver, one frame per content change, for both surfaces; a
single JumpToLatestButton replaces both chips; the 720px transcript
override is gone. DESIGN.md records the shared composer, the jump
control, the reading width and the two shadow tokens.

page.tsx still owns the chat main chain, but the first product surfaces now
live in their own modules so later splits can land without editing the 4k-line
Home. Source-lock tests follow the moved tokens; the orphan user-data contract
is aligned and added to the quick gate.

Dark muted surfaces missed WCAG AA; action and tertiary tokens plus a 32-pair contract close that. Hit targets, remaining-count, and Enter-to-send follow the interaction audit without changing visual sizes.
