Two usability gaps in the wide-pane framing tuner:
- No way to dismiss the panel. Add a × close button to the header and make
the Shift+A shortcut open/close the panel (reveal/dismiss). The A/B
enabled toggle now lives as a checkbox in the panel, so closing the panel
no longer changes the framing state.
- Edits hit every split pane at once. Add a Target selector (All panes, or a
specific pane labelled by its arrangement, e.g. "Panel 1 — Rhythm"). Per-
pane edits write a sparse override map (__panels[key]); each renderer
resolves the shared base with its own pane's overrides laid on top via
_resolveTuneFor(paneKey), so one pane can be framed independently. Reset on
a pane clears its override (re-inherits the base); Copy exports the resolved
values for the selected target. The live readout is keyed per pane.
Panes are discovered from the existing per-panel key (_bgPanelKey /
feedBackSplitscreen.panelIndexFor) and self-register each frame for the
picker. Overrides persist to localStorage alongside the base.
Tests extended in tests/js/highway_3d_wide_fov.test.js.
