During a token stream $messages is replaced ~30x/s. Subscribing the whole chat view to it re-rendered the composer, runtime boundary, and every message on every delta. - Derive coarse facts (empty thread? tail is user?) via nanostores `computed` atoms so per-token flushes don't re-render their consumers. - Move the $messages subscription + runtime wiring into a dedicated ChatRuntimeBoundary; the composer reads $messages imperatively. - Drive message rows off stable useAuiState selectors and a lazy getMessageText getter instead of eagerly materialized text. - Feed ResizeObserver entry sizes into measureClamp / FadeText and dedupe the style writes, killing the read-write-read reflow cascade.
