feat(devtools): rainbow trigger, persist strip fold, and pane gutters - #510
Merged

Conversation
Use the rainbow palm as the default trigger mark and default triggerMode to floating. Keep the folded plugin strip across reloads. Lay plugin panes in rounded cards with even gutters, theme panel scrollbars, and keep resize handles on the live layout so they stay in the gap after a pane opens or a drag.
📝 WalkthroughWalkthroughThe update changes the default trigger to a floating rainbow palm mark, persists secondary-strip folding, revises plugin workspace geometry and pointer resizing, and adds inset cards, transparent gutters, themed scrollbars, tests, documentation, and changesets.

Correct the resting-gutter release note.
The separator is transparent at rest. The PR behavior shows its resize line on hover or focus. Replace “keep pane gutters visible at rest” with wording that describes hidden resize lines or transparent resting gutters.

| - A fixed-height **44px secondary strip** for plugin and SEO navigation. It scrolls horizontally when space is limited, and a pull tab on its bottom edge folds it away behind the header. Folding changes nothing else — the panel keeps its height and the destination content keeps running — so the tab is rendered only on the destinations that have a strip. | ||

Describe the pane separators as resizable.
“Static separators” conflicts with the documented pane-resize behavior. Replace this text with wording that describes resizable splitters between plugin mount frames.
Proposed documentation change
-- Up to three simultaneous **plugin mount frames**, divided into equal widths by static separators
+- Up to three simultaneous **plugin mount frames**, separated by resizable splitters📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Document keyboard-focus visibility for the resize line.
The resize line also appears on keyboard focus. Include this behavior so keyboard users receive correct instructions.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Derive aria-valuenow from the local split size.
Lines 854-858 divide a workspace-relative coordinate by the local split extent. A nested splitter can then report a value above 100 despite aria-valuemax={100}. The outer card inset also makes root-split values inaccurate.
Add the preceding child fraction to SplitterHandle, then set aria-valuenow from Math.round(fraction * 100).

Changes
The default trigger uses the rainbow palm mark. The chip is a 56px circle.
triggerModedefaults tofloating.The plugin strip fold is stored in settings. A refresh keeps the strip folded.
Plugin panes sit in rounded cards with an 8px gutter. The resize line is hidden at rest and shows on hover or keyboard focus. Drag follows the pointer. After a third pane opens, the handle stays in the gap between cards. Whole-panel resize does not highlight page text.
Panel scrollbars use the theme.
