/**
 * Sim's audit trail told as an append-only ledger rather than a product
 * window: a frameless, centered vignette (the access tile's composition,
 * which sits beside it in the row) where each record is a plain row —
 * gradient actor avatar, the action label in the row's regular sans face
 * (`font-medium text-small`, the same treatment the standards tile gives
 * its row titles), an "actor · resource" attribution line, and a
 * right-aligned timestamp. The newest record is the selected event: it
 * sits on a solid white card wearing the build tile's window chrome
 * exactly — `--white` fill, 1px `--border-1` hairline, `rounded-xl`,
 * `shadow-sm` — while the older records rest directly on the tile,
 * quietening with age until a mask gradient dissolves the oldest —
 * implying the trail continues into history. A small "Audit log"
 * header with an `Append-only` mono ChipTag (fill stepped up to
 * `--surface-6` so the pill stays legible on the grey ground) names the
 * surface without window chrome.
 *
 * Motion (from `audit-trail-graphic.module.css`): the newest record stamps
 * in once from above — an append, never re-played, since the record is
 * immutable — and its avatar then carries the row's shared 6s ring-pulse
 * beat (matching the access tile's grant node and the lifecycle tile's
 * live node). Both are removed under `prefers-reduced-motion`.
 *
 * The avatar assets are grey radial gradients on a black square, so each
 * sits in a `rounded-full overflow-hidden` clip with a slight scale-up to
 * crop the black canvas past the circle's edge.
 *
 * The feature tile's visual slot bleeds `2rem` right (`1.5rem` under
 * `max-lg`) but not left, so this centered vignette adds matching right
 * padding to land on the tile's visible center instead of the bled slot's
 * center.
