Launch checklist

Checking a line fills the box, draws the tick, strikes the words and fades their ink, all read off one spring per row.

Where it earns its place

Launch runbooks, onboarding steps and client handover lists, where crossing something out should feel as satisfying as it does on paper.

What we changed

  • Recast as the Northstar Cloud launch runbook: vitals, schema, AI search baseline, analytics and redirects.
  • Kept the central idea: one spring per row with four readings of it, where the fill may overshoot but the tick and the strike are clamped so they never draw past their ends.
  • Kept the strike's lag window (starts at 12 percent, runs over 72) and sized the rule to the measured words, not the row.
  • Replaced the falling-heap finale with a quiet cleared state, then rows untick bottom-up so the list resets itself for the next visitor.
  • Rows are real checkboxes (role and aria-checked) with a live status line; reduced motion jumps each spring to its end.
