/**
 * Screenshots documenting the focused Inbox behavior for PR #2045.
 *
 * These replace the hand-generated shots posted earlier in that PR, which went
 * stale twice: once when the surface was briefly renamed to "Activity", and
 * again when the Projects filter landed. Keeping them in a spec means the next
 * round regenerates instead of drifting.
 *
 * Run: pnpm build:e2e && pnpm exec playwright test --project=smoke \
