   When JSON is invalid (or `disabled` is true), `handleTokenChange` silently 
returns at line 139, but the `ColorPickerControl` (lines 162-167) is still 
rendered enabled — `ColorPickerControl` has no `disabled` prop (see its props 
interface), so clicks look accepted but do nothing. Consider disabling/hiding 
the pickers when `!isValid` so the UI matches the dropped-edit behavior.

   Lines 206-209 duplicate the `colorValue` selection already computed in 
`getArrowIndicatorColor` (lines 188-191). If one copy is later edited (e.g. a 
new `percentDifferenceNumber === 0` branch), the arrow color and the pill 
background/text can silently diverge. Hoist a single `comparisonColorValue` 
local and reuse it in both places.

   <div id="suggestion">
   <div id="issue"><b>Duplicated color control config</b></div>
   <div id="fix">
   
   The new `increase_color` and `decrease_color` controls duplicate the entire 
ColorPickerControl config (`presets`, `resolveThemeTokens`, `outputFormat`, 
`renderTrigger`, `visibility` callback). If a preset or visibility rule 
changes, one control can silently diverge from the other. Consider extracting a 
shared base config object and spreading it into both, overriding only 
`name`/`label`/`description`.
