atlas 39b95c2ede treefmt: apply prettier
Pure `nix fmt` output from the commit before this one — no hand edits.
203 files: 52 md, 42 tsx, 32 js, 32 css, 21 ts, 13 html, 8 json, 3 mjs.

Reproduce with `nix develop -c nix fmt` on the parent commit; the result
should be byte-identical to this tree.

None of the 13 `.prettierignore` entries appears here — verified by
intersecting the changed-file list against the ignore file, with a
control proving the intersection finds a match when one exists.

// /logs.html entry point: log viewer with three sub-tabs (AGENT, INFRA,
// SYSTEM). Build log history lives at /builds.html, not here.
// AGENT — per-container journald viewer, backed by GET /api/journal/{name}
// INFRA — infra-container journald viewer (hive-ci, hive-forge, …),
// same API but full machine journal only (no unit filter)
// SYSTEM — host service logs, backed by GET /api/journal-host
//
// Tab routing via URL hash (#agent, #infra, #system). Default: #agent.
//
// URL params `?agent=name` and `?unit=svc` pre-select the agent + unit.
// When `?agent=` names an infra container the INFRA tab is activated instead.
// Last-fetched timestamp is shown next to the refresh button on AGENT,
// INFRA, and SYSTEM tabs so the operator knows how stale the output is.
