Whiteboard

The whiteboard editor gains multi-select, resize handles, theme toggle and text sizing, all unreachable.

Whiteboard editing gets rubber-band multi-select, eight resize handles and a theme cycle, behind a disabled skill.

What

The board editor moves from a single selection to a selection set and picks up a batch of direct-manipulation features. Still behind the constant-false whiteboard gate.

Details

selectedId becomes a Set of ids, with box-drag rubber-band selection XOR'd against the base set when shift, ctrl or cmd is held
group move applies a single snapped delta; group delete detaches surviving arrows
session storage writes selectedIds while still reading the old single-id form
shapes get eight resize handles (four corners, four edges) with matching cursors and an anchored opposite side
a 4-screen-pixel click threshold means a click no longer nudges, plus hover cursor feedback
a theme button cycles auto/light/dark, persisted under wb-theme
a text-size stepper is bound to [ and ]; text nodes may carry a size, default 17
shape labels are word-wrapped and shrunk to fit their box, with the fit cached
gate: whiteboard skill isEnabled g5v = Wms() && Ige(), and Wms returns !1

Evidence

const TEXT_SIZES = [12, 14, 17, 20, 24, 32, 40, 48];

Strings lifted out of the shipped bundle, so the claim above can be checked against them.

Other releases about the same thing. Found by shared names or similar wording; neither means one caused the other.
