A corner press during a return ended the return at the recorded
rectangle, so the panel jumped without pointer travel. The press now
picks the panel up where it is drawn for a resize as well: the resize
keeps the drawn origin and caps only the corner by the viewport, and the
release records the legal rectangle and springs the origin inside, as a
resize whose viewport shrank past its origin also does. Under reduced
motion a resize draws its legal rectangle and animates nothing.
- Move TabBody to its own module and draw DockSurface's docked bodies
through it too, so divider and tab drags no longer re-render bodies.
- State in TabRenderer when the kit calls renderTab again and reuses a
body.
- A corner press during a return ends it at the recorded rectangle; only
a grip press picks the panel up where it is drawn.
- The resistance and its inverse keep the legal size, a resize origin
stays inside a viewport that shrank mid-gesture, and a Windows root
without a published caption height keeps the 20px floor.
- The Web e2e waits for the resting style before checking the clamp.
- Tests say "does not re-render" and also show that a new renderer
re-renders the bodies.
A float drag and its return update the preview through React state, so
TabLayout re-rendered every TabHost and called renderTab for every
retained body on each frame. Both renderers now draw bodies through
TabBody, memoized on the renderer and the tab record, so such a frame
re-renders only panel frames and headers.
Measured in the Web e2e scaffold under 4x CPU throttling (median of 5,
60-step drag past the corner, then the return): with a 4000-line file
preview floating, drag scripting fell from 592 ms to 100 ms and the
return's from 180 ms to 56 ms; with the default small preview, drag
scripting fell from 121 ms to 95 ms.
The resting .float rule now caps width at 100vw and height at the
viewport below the caption floor, so a stale viewport reading cannot
leave an oversized panel's header controls or resize corner off screen.
Vertical limits use 100dvh, which follows window.innerHeight as the
gesture hook does. The Web e2e publishes a far-off, oversized resting
rectangle and checks that the stylesheet alone draws it over the viewport.
- 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.
