6// Ticket number ticker - a ticket id shown as one celebratory value.
7//
8// The pill hugs its value and grows with it up to a max-width; a short #42 is a
9// small pill, a longer id fills out toward the cap. Past the cap it uses the
10// idiom every commit-SHA and wallet-address UI already uses: MIDDLE-TRUNCATE to
11// `start…end`, keeping the two ends that identify and disambiguate and dropping
12// the middle you can recover on hover (tooltip) or copy:
13//
14//   #100000000042            → #10000…0042
15//   #billing-webhook-...2026 → #billing-…-2026
16//
17// How much survives is measured against the CAP's budget (not the current hug
18// width) - a hidden clone is binary-searched to the last `#start…end` that fits.
19//
20// Numbers additionally get the odometer run-up: each surviving digit is a reel -
21// a 1em window over a 0-9 strip - snapped to 0 then released to `10 + digit` so
22// it scrolls a full turn and lands on target, cascading left→right. Bump
23// `runKey` to play it (e.g. when a new ticket arrives). tabular-nums keeps every
24// column exactly 1ch so nothing shifts as it rolls or truncates. Drop the digits
25// entirely and it's a plain name: no reels.
26//
27// Pass `status` to show a GitHub pull-request state badge (open/draft/merged/
28// closed, GitHub's own colours); pass `onStatusClick` to make it interactive.
29// `width="fixed"` gives every pill one footprint for steady columns. As you
30// type, motion's `layout` glides the centred pill to its new spot instead of
31// snapping (position only - the width change stays instant so the new digit is
32// never clipped). Animation via motion/react; honours prefers-reduced-motion.
33// Requires the lab-theme tokens. Fully Tailwind, no CSS files.
34//
35// NOTE ON SIZE: the pill is deliberately compact (text-xl value, h-8 actions)
36// so it drops straight into dashboards, list rows and toolbars. The lab demo
37// page renders it inside a scale wrapper purely for presentation - what you
38// install is the dashboard size you see in your own app.
