A pure debounce resets its timer on every pointermove, so a real drag
(events faster than 40ms apart) never commits until the pointer pauses
or lifts — killing live preview updates mid-drag. Throttle with a
leading-edge commit + trailing flush instead.
Only onPointerDown was wired, so dragging the knob/track only ever
committed the initial click position — nothing tracked the pointer
after that. Uses the Pointer Capture API (setPointerCapture on
pointerdown, onPointerMove while captured, release on pointerup) so
the value follows the cursor continuously during a drag, matching how
the legacy native <input type="range"> control behaves for free.

The track's visible line was only 2px tall, and pointerdown was bound
directly to that thin element, making it hard to grab. The hit area is
now 20px tall (a wrapping div) with the visible line rendered as a
thin decorative child, centered inside it — the ratio math only reads
left/width so click accuracy is unaffected.

Adds a fast (120ms) CSS entrance animation for flat inspector accordion
group headers/body, gated to the group actually toggling (not derived
from remounting alone) to avoid a Chromium reflow quirk that otherwise
replays the animation on untouched collapsed siblings.
Collapsed group headers render in fixed, non-scrolling document flow
above and below the open group; only the open group's own content
scrolls, in a dedicated region. Also fixes the flat inspector footer's
missing background.

The flat inspector rendered its new Style/Grade groups AND the legacy
ColorGradingSection/StyleSections components a second time below them,
visibly doubling every control. Remove the now-redundant legacy render
call sites (and their now-unused imports) from PropertyPanelFlat.tsx;
those components stay intact for the legacy (flag-off) PropertyPanel.
FlatTextSection's multi-field branch (textFields.length > 1) now renders
FlatTextLayerList (Task 5) + the existing single-field FlatTextFieldEditor
for the active field, tracked via new local activeFieldKey state that
resyncs (useEffect) when the active field disappears from props. This
retires the legacy TextSection delegation entirely for that case; the
TextSection import is removed from propertyPanelFlatTextSection.tsx since
nothing else in the file referenced it.
Also updates propertyPanelSections.test.tsx and PropertyPanel.test.tsx,
which exercised/documented the old multi-field-falls-back-to-legacy-
TextSection behavior in comments and test titles — reworded to describe
the new flat path (assertions were already compatible and still pass).
Flag for reviewer: hideOwnHeading on the legacy TextSection component
(propertyPanelSections.tsx) was added in an earlier plan specifically for
this now-removed call site. It has no remaining consumer after this task
lands (PropertyPanel.tsx's legacy caller doesn't pass it). Left in place
per brief instruction — not deleting unilaterally, since that's a scope
decision for whoever reviews this task.

Review proved the existing test didn't catch a broken stopPropagation
by temporarily removing it and confirming the suite still passed.

Review of the pin-aware group list refactor flagged the test name
claiming the group "closes" on unpin — it doesn't assert that, and
structurally the group re-opens (togglePin never touches openGroupId).
Retitled to describe only the return-to-stack behavior actually tested.

Reads/writes the per-element-kind pinned-groups map added to
studioUiPreferences in the prior task, read-modify-writing the whole
map since writeStudioUiPreferences only shallow-merges top-level keys.
Also adds a not-busy click assertion for the Apply button so
onApplyToScope is exercised end-to-end, not just its disabled state.

Also hoists the pointerdown-drag/reset-click test scaffold shared by the
new Roundness tests and the existing Contrast/Exposure tests into helpers
(findRowByText/dragSliderTrack/clickSliderReset), and exempts pre-existing,
branch-inherited fallow findings unrelated to this task (TextFieldEditor
complexity from earlier Text-inspector commits; test-scaffold duplication
across four flat-inspector-series test files from Plans 2-4) via
.fallowrc.jsonc, per this repo's established convention for line-shift/
inherited findings.

Review of Task 6 flagged the exposure/other-key scale ternary as always
resolving to 100 on both arms.

Follow-up to 684ec4e87: that fix corrected the seek target for Layout's
keyframe gutter via deriveElementTiming, but currentPct — which drives
KeyframeNavigation's diamond active/inactive state and prev/next arrow
targeting — still used PropertyPanel's naive elStart=0/elDuration=1
basis. For an element with animations but no explicit data-duration,
seeking to a keyframe's real absolute time no longer lit that
keyframe's diamond as active, and the prev/next arrows targeted the
wrong keyframes.
Thread currentTime into PropertyPanelFlat (swapping the now-redundant
currentPct prop 1-for-1, so PropertyPanel.tsx's line count is
unchanged) and recompute currentPct there from the same
deriveElementTiming basis already used for the seek fix.

Whole-plan coherence review (Plan 3a Layout + Plan 3b Motion) found that
Layout's keyframe gutter and Motion's Timing row independently derived an
element's start/duration and disagreed whenever an element had animations
but no explicit data-duration: Motion correctly inferred the range from the
element's GSAP tweens, while Layout's keyframe gutter fell back to a naive
`duration ?? 1`, so clicking a keyframe percentage in Layout could seek to a
different absolute time than what Motion's Timing row displayed.
Extract deriveElementTiming (propertyPanelFlatTimingDerivation.ts) as the
single shared basis both paths now consume: FlatTimingRow (Motion) and
PropertyPanelFlat's own elStart/elDuration (Layout's keyframe gutter and 3D
Transform block). PropertyPanelFlat now recomputes this basis itself from
its own element/gsapAnimations props instead of trusting the parent's naive
value, so PropertyPanel.tsx (and its legacy non-flat panel) is untouched.
