/* ===========================================
   Audit Log (projects/audit_log.html), theme v6: page head with the two
   switches, a filter row (native selects inside .filter chips, the range
   picker) and one card holding the feed. A row: chevron, time, avatar,
   actor + what + key details, category tag, result; it opens to the full
   detail. Day separators are the global .chat-date-sep (localtime.js).
   Reuses primitives.css (.page-head, .filter, .micro, .avatar, .list-foot,
   .link) and badges.css (.badge.mono.purple for "via …").
