/**
 * One job's Activity view (#249 Activity-1, D56): `#/activity/<id>`, the approved mockup `activity-scan.html` in the
 * concept's classes.
 *
 * - Header: the page heading names the job; its line is the Activity item's (D54), and its actions are Download report
 *   (the job's JSON report, D59) and, while the job runs, "Cancel scan" (danger). D87: an ended scan that recorded
 *   Needs review items adds the concept's **Review metadata** after Download report.
 * - Progress (`section.surface`): `<progress>`, the server's "Processing file N of M · about X min left", and the
 *   outcome counters as `dl.stat-row` tiles: Added to Library (green), Already known, Needs review (warning), No usable
 *   metadata, Errors (red).
 * - Results (`section.surface`): the outcome list (`button[aria-pressed]` with counts, in the mockup's order), a path
 *   filter, and the selected outcome's listed rows (at most 200 per outcome, so "Showing N of M"). Rows under Added and
 *   Already known open the file in the existing viewer through its listing identity (D57); the others are plain text.
 * - Log: `details.term` "Scan log", collapsed, holding the raw timestamped lines in `pre[tabindex=0]`.
 * - D89: the tiles, the outcome list, the openable rows and the log and cancel labels are the job kind's (`jobView`):
 *   an image tagging job shows Tagged, Unchanged, Skipped and Errors, opens Tagged and Unchanged rows, and reads
 *   "Tagging log" and "Cancel tagging".
 * - D101 (System S7): a finished duplicate search that found groups adds **Review groups** after Download report; it
 *   opens "Review duplicate image files" for this search.
 * - D111: the kind's descriptor (activity-kinds.mjs `viewOf`) decides them for every kind: a thumbnail job counts
 *   Generated, Skipped and Errors; a kind without groups (the health check, a held legacy-page operation) shows no
 *   tiles and no Results, never another kind's zeros. A job without a known total has an indeterminate `<progress>`;
 *   only a job the server can stop shows Cancel.
 *
 * The summary follows the Activity store (one SSE stream per running job); the listed rows and the log are read from
 * `GET /prompt_manager/jobs/<id>` at most once a second while the job runs, and once more when it ends.
