- Add a native resolution COMBO (shipped sizes only) so a size can be picked
and saved in the workflow without the panel; custom or unparseable labels
fall back to width/height on both sides.
- Mirror the dropdown with the chips: options follow the active chip, the
value tracks the current size, and picking a label writes width/height.
- Draw a decorative ratio shape on each ratio chip and show the first
families warning in the status line.
- restore keyboard focus to the equivalent button after each render
- keep the accent background when hovering a pressed chip or size
- refresh the panel when input links change
- treat a size listed in the clicked chip as a no-op
- add resolution picker view with chip grid, size list and custom ratio input
- add extension that projects native widgets and writes sizes via callbacks
- add browser tests for rendering, theming, idempotent mount and disposal
