Daily Product UI Teardown

Linear's issue detail panel holds more design decisions per square pixel than almost anything in SaaS

A deep teardown of Linear's issue detail view — the two-column screen that packs 14+ metadata fields, a full comment thread, and a state machine into a surface that feels calm. Breaks down the three-tier information hierarchy built on a single chromatic slot, whitespace used as semantic grouping logic, a full state change inventory, and the micro-interaction mechanics behind keyboard dispatch and component reuse. Closes with three portable design principles any PM can apply.
