/**
 * audit — the append-only trail.
 *
 * Shared primitives live in style.css and are reused rather than restated: `.toolbar`,
 * `.scroller`, `.absent`, `.muted`, `.loading`, `.view-error`, `button.primary`.
 * Everything here is scoped to `#view-audit` so no other view inherits it.
 *
 * Three rules from DESIGN.md govern most of what follows:
 *
 *  - The registration offset is the one permitted depth device and it belongs on a
 *    document plate. The register is the document this screen exists to produce, so it
 *    carries the offset and nothing else on the screen does — the filter plate above it
 *    is ruled and ticked instead. The offset is `3px 3px 0 0 var(--ink)` and it is
 *    declared once, so no breakpoint can shrink it.
 *  - Marking Orange is legal at 24px and above. The only orange on this screen is the
 *    Search button's ground, which is `button.primary` from style.css and pairs ink on
 *    orange at 5.3:1. Nothing here adds a second one, and the diff does not spend the
 *    marking signal on a value that used to be something else.
 *  - Mono is for measured values. Stamps, action keys, target ids, uids, field names and
 *    stored values set in mono; every sentence on the screen — including a stated reason
 *    and a stored string running past about six words — sets in Archivo.
