Past the cap it uses the\n// idiom every commit-SHA and wallet-address UI already uses: MIDDLE-TRUNCATE to\n// `start…end`, keeping the two ends that identify and disambiguate and dropping\n// the middle you can recover on hover (tooltip) or copy:\n//\n// #100000000042 → #10000…0042\n// #billing-webhook-...2026 → #billing-…-2026\n//\n// How much survives is measured against the CAP's budget (not the current hug\n// width) - a hidden clone is binary-searched to the last `#start…end` that fits.\n//\n// Numbers additionally get the odometer run-up: each surviving digit is a reel -\n// a 1em window over a 0-9 strip - snapped to 0 then released to `10 + digit` so\n// it scrolls a full turn and lands on target, cascading left→right. Bump\n// `runKey` to play it (e.g. when a new ticket arrives). tabular-nums keeps every\n// column exactly 1ch so nothing shifts as it rolls or truncates. Drop the digits\n// entirely and it's a plain name: no reels.\n//\n// Pass `status` to show a GitHub pull-request state badge (open/draft/merged/\n// closed, GitHub's own colours); pass `onStatusClick` to make it interactive.\n// `width=\"fixed\"` gives every pill one footprint for steady columns.

Animation via motion/react; honours prefers-reduced-motion.\n// Requires the lab-theme tokens. Fully Tailwind, no CSS files.\n//\n// NOTE ON SIZE: the pill is deliberately compact (text-xl value, h-8 actions)\n// so it drops straight into dashboards, list rows and toolbars.
