- A release that reaches the press's legal rectangle only raises, so a
click on a panel drawn projected no longer records a move or resize.
- The return starts at the drawn panel's speed, and launchVelocity caps
its outward part so the whole trajectory stays within 120 px.
- A panel larger than the viewport draws at the viewport's size, keeping
its header controls and resize corner reachable.
- A return ends on an undo, dock or close of its panel, and at its target
when another panel is pressed; a gesture uses the bounds of a window
resized mid-gesture; drawn samples outside the velocity window drop.
- Gestures and returns may draw above the top floor; at rest the .float
rule clamps every panel into the viewport and below the caption floor.
- Web e2e drags a Sidebar float past the right and bottom edges.
- The note is renamed to spring-based edge recovery, compressed, and
cross-linked to the docking and retained-layout notes.
