The standalone pages (/flow, /logs, /stats, /settings) all share the same
sticky back-link header, but its CSS lived in the dashboard's common.css
under the misnomer `.logs-*` (the comment even noted it was used by more
than logs). Promote it to a first-class shared component.
- new @hive/shared/chrome.css with neutral `.page-header` / `.page-back` /
`.page-title` (cohering with the `.page-content` gutter wrapper);
exported from the shared package and @imported into common.css next to
base/terminal/tabs.css.
- rename the four pages' header markup `.logs-*` → `.page-*`.
- drop the old `.logs-*` chrome block from common.css; refresh the stale
doc comments in settings.css / stats.css / dashboard.css.
CSS-only, behaviour/visual-neutral (same rules, new names + home). The
dashboard keeps its own richer sticky `.dashboard-chrome`; unifying the
per-agent UI's `.stats-nav` chrome is a larger follow-up, deferred.
Part of #1464 step 3.
Extracts the hive-wide turn-stats rollup out of the dashboard tab strip
into a standalone /stats.html page, reached from the H0M3 hub — same
minimal-chrome pattern as /flow.html and /logs.html. The dashboard tab
strip is now purely operational.
- new stats.{html,css,js}; stats.js holds the moved render JS and
fetches /api/stats-hive on load + window change.
- migrate the window selector (#hive-stats-windows) from a bespoke
data-w/.active toggle to the shared createTabStrip — now hash-routed
(#1h / #24h / …) and deep-linkable, matching the per-agent /stats page.
- drop the ST4TS tab + pane from dashboard.html and the hive-stats render
block + the stats->refreshHiveStats lazy-load from tabs.js.
- move the shared .hive-stats-table to common.css (the dashboard SYST3M >
C0NT41N3R L04D table still uses it); the ST4TS-only window/chip/bar
styles go to stats.css.
- add a Stats tile to the H0M3 hub (and drop the now-stale "stats" from
the Dashboard tile desc); wire build.mjs + the nix/frontend.nix manifest.
Second slice of #1464 step 2; follows the /settings.html extraction.
