Period Line V2 Live-Browser 101-Frame Contact Sheet
A complete 101-frame browser-rendered sequence used to inspect the Period Line V2 wordmark handoff, connected line reveal, loop traversal, reading-block entrance, and final composition as one continuous motion system.

Evidence Role
This is the core motion-review artifact from the Period Line V2 task. It turns a long scroll-linked animation into a scan-friendly grid, making discontinuities and timing relationships easier to see than in code, tests, isolated screenshots, or repeated manual replay.
What It Made Visible
- The opening word and vertical line share one axis.
- The word-to-header handoff precedes the routed loop.
- The visible path remains connected as it advances through the loop.
- The reading block appears only after the line clears its text area.
- The final composition can be compared directly with every intermediate frame.
Method Lesson
The contact sheet is evidence only when its capture conditions match the experience under review. This sequence is linked to the task that discovered settled headless captures could hide live scrub defects, so browser, viewport, DPR, scroll method, and settle behavior must travel with future motion sheets.
