ns-ui / nav-condense-rail
The distance this bar takes to go from roomy to dense is read off its own rendered height at each extreme — shrink the wordmark, change the font, resize the window, and the transition still ends exactly where the bar itself stops shrinking.
Case studies, shipped product, the occasional postmortem. Scroll to watch the bar above tighten from roomy to a dense pinned rail — the transition length is measured from its own height, not a guessed pixel value.
Discovery, prototyping, build, handoff. Four sections, no filler beyond what makes the page tall enough to scroll through the condense.
Flat project rate, no retainer required. Scroll back up and the bar reopens to its roomy resting state at exactly the same measured distance.
