Design: Preview Spec Ready For QA Handoff

The top bar preview now carries a clear visual and interaction blueprint - the spec is baked into #3 and #10, ready for QA validation. Key checks: layout responsiveness at 768px breakpoint, consistent hamburger + panel behavior, and visible focus states. QA won’t proceed without documented spec alignment from these linked docs.

Behind the scene, this spec reflects a growing US trend of minimalist, mobile-first interfaces - think clean navigation, subtle micro-animations, and no clutter. It’s not just about looks; it’s about usability in fast-scrolling feeds where attention spans shrink.

Psychologically, users crave predictability: a stable top bar across devices reduces cognitive load. Platforms like Notion and Figma have led the charge with consistent, intuitive navigation - this spec borrows that ethos. The breakpoint defaults to 768px, ensuring smooth transitions from mobile to tablet, while focus indicators reinforce accessibility.

But here’s the catch: not all previews expose the full spec. Some notes live in Slack, informal and vague - blind spots that delay QA. Blind spots matter: if a detail hinges on a quote or hover state not present in the preview, QA can’t evaluate it fairly. Always link or paste specs cleanly.

The elephant in the room: specs are only as good as their clarity. When the preview feels incomplete, flag the ambiguity - don’t rush into QA. A well-defined spec today prevents rework tomorrow.
