One circular FAB (peer-count badge) replaces the top-right overlay row:
draggable anywhere (pointer capture, 4px click-vs-drag threshold — the
comment-pin pattern), position persisted in localStorage, panel opens
toward screen center and stacks composable sections — roster, source chip,
view-only pill, follow row, comments, chrome toggle. Renders at z-50 above
everything (decided: covers wx dialogs; trivially dismissed via click-away/
Esc/drag). CommentLayer portals its bar + list panel into the menu's
comments slot; pins/popovers/composer/click-catcher stay canvas-anchored.
The FAB is the chrome-hidden survivor. e2e specs updated with an
openOverlayMenu helper (panel is closed by default, click-away closes it).
NOTE: Playwright suites updated but not executed here (no local WASM
artifacts) — verify on CI / next session.

emitViewportIfChanged deduped on scale+center only, so a canvas SIZE change
(boot layout settling after the bind-time seed, window resize) never re-pushed
{w,h} to JS. CommentLayer's worldToScreen maps through h/2, so every DOM pin
hit target (and its hover ring) sat vertically offset from its GAL dot by
exactly delta-h/2 css-px until the next pan/zoom finally passed the dedupe.
Size now participates in the dedupe and wxEVT_SIZE re-pushes post-layout
(CallAfter, after the GAL's own onSize). New regression e2e
comments-viewport-resize.spec.ts asserts the DOM pin re-aligns with GAL truth
(fresh kicadCollabGetViewport) across a window resize with no pan/zoom.
