/* Sprint 0.3.1c-CLAIM-VIZ V.2 (2026-05-06) — claim attribution badge.
   Inline indicator next to slide title in the project dashboard's
   work-slides folder. Renders for any slide with claimed_by populated;
   provides at-a-glance "who has what claimed" oversight for admin /
   evaluator walking the dashboard. Existing tokens only — no new
   tokens introduced. The lock icon is a 10×10 inline SVG
   (currentColor stroke), kept terse to fit alongside the question
   and returned-revision badges without breaking title density. */
