Apply the cheap visual wins from the BW Event Report layout:
1. Channel order reversed → MicL (top), Long, Vert, Tran (bottom)
to match the Instantel printout.
2. Shared bottom time axis — x-axis ticks only render on the
bottom-most data channel; other channels hide ticks so all four
visually share one time scale.
3. Triangle trigger markers above and below the t=0 dashed line.
4. Horizontal zero-baseline (dotted) per channel with "0.0" label
on the right edge — Instantel convention.
5. "Print view" toggle that flips dark→light theme (white panels,
light grids, dark text) so the viewer can render usefully on
paper-style output / @media print.
6. Per-channel PPV stats table in the metadata header, with Peak
Vector Sum displayed prominently.
7. Colors adjusted to approximate BW trace colors (magenta MicL,
blue Long, green Vert, red Tran).
Future PDF-export work will reproduce the same layout server-side
once you upload a real example PDF and we pick a rendering pipeline
(weasyprint / chromium --print-to-pdf / etc.).

New standalone HTML page (sfm/event_browser.html, ~470 lines, Chart.js)
that lets you browse persisted events from the SeismoDb + WaveformStore.
Companion to the existing live-device viewer at /waveform:
/waveform — connect to a unit and pull events in real time
/events — browse events already stored in the DB
Flow:
1. Page loads → GET /db/units → populate serial dropdown
2. Select serial → GET /db/events?serial=X&limit=500 → event list
3. Click event → GET /db/events/{id}/waveform.json → render
Layout is Instantel-printout-ready: channels stacked vertically in
Tran / Vert / Long / MicL order, trigger line at t=0, peak labels,
clean dark theme. Frames the future PDF-export feature without
needing extra layout work.
Smoke-tested against the dev prod-snapshot — 4 channels render with
correct peaks for K558 events (L=0.3 in/s = the offset-fault peak
we've been chasing all week).
CHANGELOG entry added under [Unreleased] per the v0.20.0 release plan.
