What

Keyboards with no art of their own now show a keyboard placeholder instead of the mouse one. The new image is a black keyboard silhouette with a white question mark, the keyboard version of unknown-device.png.

This covers:

• every device the app labels a keyboard (kind: "keyboard")
• any device whose reported name contains "keyboard"

The placeholder shows in the device hero, the sidebar device list and the devices home. A keyboard image that fails to load falls back to the keyboard placeholder, not the mouse one (new placeholderImage(kind)). A keyboard that has its own art (for example Keychron M6) keeps it.

Removed (replaced by the new placeholder)

• src/shared/KeyboardArt.tsx and its three .keyboard-art* rules in advanced.css. This was the drawn stand-in used only for Arbiter keyboards in the device hero. Arbiter boards now show the placeholder.
• public/devices/keychron-keyboard.svg. This was the generic outline for Keychron HE/TMR boards. Those now resolve to the placeholder.

Image

public/devices/unknown-keyboard.png: 1428×716, transparent, 6.5 KB. It is served locally through LOCAL_OVERRIDES until a maintainer uploads it to the R2 bucket. public/devices/README.md has the provenance note and the upload follow-up.

The outline was traced from a pngtree stock render of a 60% keyboard. Only the shape carried over: no colour, keycaps or legends. Please confirm you're comfortable with the source before merging.

Checks

• npm run build passes
• npm test: 635 tests pass, including new tests for kind-based and name-based resolution and the load-error fallback
• npm run size passes

Note

Add keyboard placeholder image for devices with no keyboard art

• Adds a keyboard placeholder PNG in public/devices/ and a DeviceImageKind type (mouse / keyboard) in device-images.ts
• deviceImage and the new placeholderImage take a device kind. Unknown or failed-load images now pick the keyboard placeholder for keyboards (by kind or a name containing “keyboard”) and the mouse placeholder otherwise
• Removes the inline KeyboardArt SVG illustration from DeviceHero, along with its styles and shared component. Keychron Hall-effect/TMR names without art now resolve to the keyboard placeholder
• Updates callers in AppSidebar.tsx, DeviceHero.tsx, and DevicesHome.tsx to pass the device kind
• Behavioral Change: deviceImage calls without a kind still default to the mouse placeholder, except names containing “keyboard” now return the keyboard placeholder; the Keychron SVG asset is deleted from public/devices/

Summary by CodeRabbit

• Bug Fixes
  • Keyboards without custom artwork now display a keyboard-specific placeholder instead of a generic silhouette.
  • If a device image fails to load, the app now displays a placeholder matched to the device type.
  • Keyboards with their own artwork continue to display it.

Walkthrough

Keyboard image resolution now uses a shared placeholder for keyboards without matching artwork. Device views pass device kind to image lookup and use kind-specific placeholders after load errors. DeviceHero no longer uses the KeyboardArt SVG illustration.

Changes: Keyboard Image Fallbacks

Layer / File(s)	Summary
Placeholder resolution and asset mapping src/shared/device-images.ts, src/shared/device-images.test.ts, public/devices/README.md	The resolver adds keyboard-aware placeholder selection and maps Keychron Hall-effect names to unknown-keyboard.png. Tests cover keyboard and mouse placeholders and retained device-specific artwork. The README records the image source and local-serving notes.
Device list image fallbacks src/app/AppSidebar.tsx, src/features/devices/DevicesHome.tsx	Both views pass device kind to image lookup and use a matching placeholder when an image fails to load.
DeviceHero keyboard fallback src/features/devices/DeviceHero.tsx, src/shared/KeyboardArt.tsx, src/styles/areas/advanced.css	DeviceHero uses the keyboard placeholder for keyboard image errors when no custom artwork is supplied. The KeyboardArt component and its CSS rules are removed.

Merge Risk: Low · up to 10096

The keyboard fallback is mergeable with a small testing follow-up: the hero's error-handler selection remains untested, although the inspected connected-keyboard path selects the correct placeholder.

Full details: Title check

Explanation

The title names the main change: a keyboard-specific placeholder image for keyboards that have no artwork. The changeset adds unknown-keyboard.png as the keyboard placeholder, adds placeholderImage and DeviceImageKind selection in device-images.ts, uses the placeholder in the device hero, sidebar, and devices home, and removes KeyboardArt. The title does not mention the removal of KeyboardArt or the Keychron outline replacement, but those are secondary to the main change. The conventional-commit prefix feat(devices): matches the scope of the change.

Explanation

Docstring coverage is 28.57% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 7 functions across 5 files.

Approvability

Verdict: Approved at 10096fa

Macroscope's review found this PR approvable — This replaces generic keyboard illustrations with a shared keyboard placeholder in device views and image-error fallbacks. The change is limited to presentation, preserves existing product artwork, and introduces no material operational or customer-data risk.

src/shared/device-images.test.ts: 1

371-374: Trivial · Maintainability & Code Quality · Low value

Cover the keyboard load-error branch in DeviceHero, not only placeholderImage.

The test the load-error placeholder follows the device kind calls only placeholderImage. The onError handler in src/features/devices/DeviceHero.tsx:85 selects the kind separately: placeholderImage(keyboard && !snapshot.deviceArtwork ? "keyboard" : "mouse"). No test renders DeviceHero or dispatches an image error event. Changing line 85 to always pass "mouse" would leave every current test passing.

The repository has no component-rendering test setup. package.json lists no DOM or rendering test library, and no *.test.tsx files exist.

Renaming the test corrects only its title. It does not cover the handler.

Move the kind selection into an exported pure helper in src/shared/device-images.ts. Call that helper from the onError handler, and test the helper directly. Keep the test title aligned with what it exercises.
