Add Per-Corner Roundness to Rectangle Path: a checkbox (off by default) and four Pixels properties (top-left, top-right, bottom-right, bottom-left). New rectangles initialise the four values from their Roundness, so ticking the box keeps the shape; the radii are animatable and expression-driven.\n\nrect_radii() builds the path clockwise from the top-left with kappa quarter-circle arcs. Overlapping radii scale down like CSS border-radius; negative and non-finite radii are square; rect() delegates to it, so uniform roundness clamps to half the shorter side as before.\n\nLottie rc has one r: four equal static radii export as that value; mixed or animated radii export roundness 0 with a warning. Import puts r into the four per-corner values so ticking the box on an imported rectangle keeps the shape.\n\nTests: path geometry and clamping, rendered per-corner pixels, Lottie equal/mixed/checkbox-off export.
The menu only carried Mute, so unmuting meant the timeline's context menu.
Add the second row bound to `keys.setMuted {"muted":false}`, its translation
in the ten catalogs, and a test that runs both rows through Session::execute
with undo and redo.
Add a muted flag to Keyframe. Muted keys stay in the Timeline and Graph Editor (dimmed, selectable and movable) but evaluation skips them, so the active neighbours interpolate as if they were not there; auto-Bezier and eases use the active neighbours. When every key is muted the property falls back to its static value.\n\nkeys.setMuted {muted} mutes or unmutes the selected keys in one undo step. The Timeline context menu offers Mute/Unmute Keyframes and the Animation menu has Mute Keyframes. Muted keys have no Bezier handles and motion-path points are dimmed.\n\nLottie export omits muted keys (with a warning) because Lottie has no mute state; scripting keeps seeing them in numKeys/key().\n\nTests: keyframe evaluation (linear, auto-Bezier spatial, all muted), serialization and value replacement, engine command + undo, Lottie export.
Text strokes were always drawn with round joins. The document gets a
Line Join (`lineJoin: miter|round|bevel` in layer.setText / newText),
Miter for new text as in After Effects, Round for documents saved before
it so their look is kept. The 2D and Advanced 3D (extruded) text strokes
use it, expressions' style copies carry it, and the Character panel has
Miter / Round / Bevel buttons under the stroke width.

A project can name /dev/zero, a FIFO or a folder as footage; reading those whole
never ended (or ran out of memory). The media layer's whole-file reads (probe,
pool, model side files) and the engine's FsServices::read_file now open the file,
refuse a non-regular one, and reserve its length fallibly, so a sparse file that
claims more than memory is an error too.
