Fake log streaming by re-fetching the podman-logs tail every 2s from the
frontend (HTMX every 2s) — the pragmatic stand-in until a real TTY/streaming
channel (v0.4 #13), per the agreed Ch3 scope.

log_viewer polls load, every 2s with hx-sync="this:drop" so slow/offline
devices can't pile up requests.
Multi-deployment selector: the poll URL is driven by hx-include of the
<select> rather than a baked deployment, so changing the selection is
picked up by the next poll instead of polling a stale deployment's URL.
Single/no deployment bakes it into the URL as before.
app.js: tail-follow only when the user is already at the bottom, so the 2s
poll doesn't yank them down while reading history.
Render tests lock the polling trigger and the selector-driven URL behavior.

Deferred: the LogQuery<T> Score companion. It's meant to mirror the
smoke-test contract, which doesn't exist yet (Ch10) — building it now would be
a speculative abstraction at n=1. Revisit when the smoke companion lands.
