- Peel-off undock drops the floating composer under the cursor (centered
horizontally, preserving the vertical grab offset) instead of snapping to
the docked corner.
- Unify the / · @ · ? completion drawer and the attach (+) menu onto one
shared glassy panel primitive (composerPanelCard): smallest theme font,
hairline border, nous shadow; floats off the composer, inset from the left.
- Directive chips: Backspace removes the chip + its auto-inserted trailing
space atomically (no orphaned space), and a phantom trailing block left by
contenteditable no longer falsely expands the composer to two rows.
- Model picker: scroll area capped at max(150px, 30dvh); footer rows aligned
(matching icons, dropped a redundant margin).
- Composer focus shifts the border ~15% toward foreground (no fill change);
input is cursor-text; trimmed control icon/button sizes.
