feat: foldable device fold/unfold Easter egg - #141
Conversation
Chromium/Samsung-Internet-only Device Posture API support: dims the hero name and plays a short click on fold/unfold. No-ops everywhere else, including Safari, since WebKit has no committed position on the API. Closes #140 Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Q98uKFMy1UNXbr34t5P4Wc

📝 WalkthroughWalkthroughThe change adds a Chromium-only foldable-device Easter egg. It detects device posture, plays fold and unfold audio, and dims the hero author name when the device is folded. ChangesFoldable device Easter egg

Merge Risk: 🟡 Moderate · up to The Easter egg may play a fold or unfold sound on the initial posture read, and its new folded-state CSS is reported to violate Stylelint. The impact is limited to foldable users and validation, but both issues remain unresolved before merge. 🚥 Pre-merge checks | ✅ 3 | ❌ 2❌ Failed checks (1 warning, 1 inconclusive)

Full details: Linked Issues checkExplanation The reviewable changes implement the posture hook, fold/unfold handling, CSS visual effect, feature detection, and decorative scope. The required user-gesture audio arming and audio asset licensing and duration cannot be verified from the available summary. Both audio files were excluded by the !**/*.mp3 path filter. Resolution Provide evidence that audio playback is armed through an existing user gesture without a new global click listener. Verify that public/audio/device-fold.mp3 and public/audio/device-unfold.mp3 are short, under 300 ms, and license-clear; these files were excluded by the !**/*.mp3 path filter. Full details: Docstring CoverageExplanation Docstring coverage is 50.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff.

Ignore the first detected posture.
useDevicePosture() initializes to undefined, so the first detected posture triggers audio.play() during page load. Require previous !== undefined before playback.
