feat(layers): add Style panel button to layer cards

[giswqs]

Summary

• Add a palette button to each layer card that selects the layer and opens the Style panel, so styling no longer requires digging into the overflow menu.
• Let the layer card action row wrap so the extra button does not overflow on narrow panel widths.
• Document the new action in the Layers user guide.

Test plan

• pre-commit run --files apps/geolibre-desktop/src/components/panels/LayerPanel.tsx docs/user-guide/layers.md e2e/layer-panel.spec.ts (build + eslint clean)
• npx playwright test e2e/layer-panel.spec.ts (3 passed, including the new "opens the selected layer in the Style panel from its card" spec)
• Manually confirm the button appears and the action row wraps at a narrow layer panel width

Summary by CodeRabbit

• New Features

  • Added an Open Style panel action to each layer card.
  • Selecting the action selects the layer and opens its styling controls.
  • Layer action controls now wrap when space is limited.
  • Improved keyboard interaction for layer cards and action buttons.

• Documentation

  • Updated the layer guide with instructions for opening a layer’s Style panel.

• Tests

  • Added end-to-end coverage for mouse and keyboard activation of the Style panel.

📝 Walkthrough

Walkthrough

The layer panel now supports a direct action to select a layer and open its Style panel. Layer controls wrap when needed, nested keyboard events do not trigger card selection, and tests cover mouse, Enter, and Space activation.

Changes

Layer style panel access

Layer / File(s)	Summary
Layer card style action apps/geolibre-desktop/src/components/panels/LayerPanel.tsx	Layer actions wrap onto multiple lines. Nested controls handle their own keyboard events. An optional palette button selects the layer and opens the Style panel.
Documentation and end-to-end validation docs/user-guide/layers.md, e2e/layer-panel.spec.ts	The guide documents the action. Playwright tests verify mouse, Enter, and Space activation and the selected layer name.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to efe84

The new Style action is covered by automated behavior tests, but the narrow-panel layout still needs confirmation because the added control could overflow or become difficult to reach at small widths. The PR is otherwise mergeable with explicit owner follow-up on that visual check.

Poem

A palette button selects with care,
And opens the Style panel there.
Enter and Space now work just right,
While controls wrap when space is tight.

Bugs

• e2e/layer-panel.spec.ts:121 — The new test asserts stylePanel (getByRole("complementary", { name: "Layer style" })) has count 0 before any layer is styled. But StylePanel mounts by default (stylePanelVisible defaults to true) and starts collapsed to its rail, rendering <aside aria-label="Layer style (collapsed)">. Playwright's getByRole name matching is substring-based by default, so "Layer style (collapsed)" matches { name: "Layer style" }, meaning the initial toHaveCount(0) assertion looks like it should actually see count 1. This contradicts the PR's claim that the test passed locally, so either there's a default-settings difference I'm not seeing, or the assertion is unreliable/flaky. Confidence: medium — I traced the default state through useDesktopSettings.ts and StylePanel.tsx but couldn't execute the suite to confirm at runtime.

Security

• None found.

Performance

• None found; the change is a small conditional render plus a CSS class tweak (flex → flex flex-wrap), no perf-relevant impact.

Quality

• The new icon button and the pre-existing "Open Style panel" dropdown menu item now perform the exact same action (selectLayer + onOpenStylePanel) side by side. This appears intentional per the PR description (a shortcut on top of the existing menu entry) rather than a defect, so just noting it — no action needed. Confidence: low (style preference, not a bug).

CLAUDE.md

• No violations found: the reused i18n key (layers.openStylePanel) already existed across all locale files prior to this PR, Palette was already imported, and the docs update in docs/user-guide/layers.md is consistent with existing conventions.

Overall the production code change (LayerPanel.tsx) is small, consistent with existing patterns (mirrors the identify button's stopPropagation/selectLayer handling), and correctly gated on the existing optional onOpenStylePanel prop. The one substantive concern is the new e2e test's initial assertion, flagged inline.

to return when e.target differs from e.currentTarget, preserving the card

that the palette button is available only when the built-in Style panel is

Code review

I reviewed the diff (LayerPanel.tsx, docs/user-guide/layers.md, e2e/layer-panel.spec.ts) along with the surrounding code for onOpenStylePanel, selectLayer, the existing overflow-menu "Open Style panel" item, and the i18n keys/strings the new e2e tests assert against. No inline comments were posted — nothing rose to a level worth flagging.

Bugs: None found. The new palette button mirrors the existing DropdownMenuItem at line 3537 (selectLayer(layer.id); onOpenStylePanel();) exactly, so behavior (including the fact it's only rendered when layoutOptions.stylePanelVisible is true, per DesktopShell.tsx:2296/2323) is consistent with the pre-existing pattern rather than a regression.

Security: None found. No new external input handling, no injection surface.

Performance: None found. The change adds one conditionally-rendered button and a flex-wrap class; negligible impact.

Quality:

• The e.target !== e.currentTarget guard added to the card's onKeyDown (line 3212-3216) is a genuine, well-targeted fix: previously, pressing Enter/Space while focused on any nested interactive control (visibility toggle, move up/down, zoom, identify — not just the new button) would bubble into the card handler, which called preventDefault() and ran card-selection logic instead of letting the native button activate. The fix is correctly scoped and covered by the new "opens the Style panel from the layer card by keyboard" e2e test. Confidence: high (verified by reading the visibility-toggle button, which had no keydown stopPropagation and would have hit the same bug).
• Minor/low-confidence nit: no e2e test covers the case where onOpenStylePanel is undefined (i.e., stylePanelVisible: false), verifying the button is absent. Given the identical pre-existing gating on the dropdown item, this is a small coverage gap rather than a defect.

CLAUDE.md: No violations. New user-facing string uses t() (layers.openStylePanel, already present in en.json and all 18 other locale catalogs — reused from the pre-existing dropdown item, no new key needed), doc update follows the existing user-guide bullet format, and the styling change uses Tailwind utility classes consistent with the rest of the file.
