Rumbleback v0.3.0

Released 2026-10-10.

New

• Rest a mouse on a dot that has lit up and a card says what it is. A seismometer gives its distance and the time the
  analyst picked next to the time the model gives. A strong motion instrument gives its network, intensity, peak
  acceleration and peak velocity. A felt report gives the number of responses and their intensity. A finger does not
  open it, because a tap drops the pin.
• A screen reader is told when the P wave, the S wave and the alert reach your pin, with the seconds that are left. Nothing
  is read out while you scrub or jump to another moment.
• The video clip is saved as MP4 where the browser can record it, so it plays on an iPhone, in WhatsApp and in social
  apps. A browser that records only WebM still gets WebM.
• A phone held sideways keeps the map. The panel stays at the side, the timeline is one row without the seismogram strip
  and the share dialog drops its preview, where before the panel and a tall timeline covered nearly the whole screen.
• A link to a quake USGS does not have says so and offers no retry. A quake that fails to load no longer says
  "Loading real station data" and no longer shows an empty magnitude box.

Fixed

• On a phone the numbers of a new pin sat below the part of the sheet you could see. A new pin now scrolls the sheet to
  them, and removing the pin scrolls it back to the quake.
• The controls ignored the notch and the home indicator of an iPhone, which the page extends under. The top bar, the
  panel, the layer chips and the timeline now keep clear of them, whichever way the phone is held.
• Safari 17 and older drew no blur behind the panels, because it knows only the prefixed property.

Tests

• New browser tests for the hover cards, the screen reader messages, the phone sheet, the safe areas and the failed
  load, a check that a recorded MP4 starts with a valid header, and unit tests for the clip format and for telling a
  missing quake from an unreachable USGS.
