hookecho: baixar versions anteriors

Second R18 checkpoint. The phone gets the same chrome the desktop got in
alpha.1, onboarding stops asking questions, and the data lanes land. Still a
prerelease: a few lanes (RRFS, the remaining store submissions) come at 0.12.0.
The phone
- The persistent bottom sheet and the five-slot toolbar are gone. The phone
draws the same floating chrome the desktop does — search pill, control
column, scrubber — with content in Material modal sheets instead of a
drawer. Predictive back still works.
- Long-press the map to inspect what is under your finger, double-tap and drag
to zoom with one hand, swipe sideways between panes.
- Haptics: ticks as the scrubber crosses a frame, a buzz when a warning lands
on you, a bump when a sheet snaps.
- Tablets and landscape phones get a side rail and a docked drawer instead of
sheets.
- Widgets show how far the nearest storm is. A battery-saver mode stretches
the poll cadence and throttles repaints. On a chase, the next radar down the
road is prefetched before you need it, and a chase can be replayed against
the archive afterwards.

Getting started
- The setup wizard is gone. First run finds you, picks the nearest radar and
draws it — about ten seconds, no questions.
- Notification permission is asked for when you turn on something that
notifies, or when a warning lands near you. Never at install.
- One help hub behind ?: glossary, hotkeys, the tour and what's new, all
searchable in one place. Labels across the app read in plain language, with
the abbreviation kept in parentheses for anyone who wants it.
- Text products — area forecast discussions, tropical advisories — render in a
real webview with real typography, on both desktop and Android.

Weather
- GOES loops run over archive dates alongside the radar timeline, and the
mid-level water vapor bands are selectable.
- MRMS rotation tracks (30/60/120 minutes) are field layers now, and hail
swaths accumulate locally over a window you choose.
- Snow squalls and banding get their own emphasis in winter.
- An alert rule can trigger on a lightning jump — the rate of change of flash
density inside a cell.
- NAM nest and NBM join the model list. Synoptic mesonets join the surface
obs, with your own API key.
- Cells are ranked by a composite severity score, and tapping one opens the 3D
volume already centered on it.
- Panes remember their own thresholds and field layers. Events can be saved as
replay bundles — time range, site, camera — and replayed with archived
radar, warnings, reports and outlooks in sync.

The web build
- Installable as a PWA, with the app shell cached offline.
- Tiles, volumes and palettes persist between visits.
- File dialogs, GPS and notifications all work in the browser now.
- A share button writes a permalink that carries the site, camera and time.

Elsewhere
- MQTT publishing, a Home Assistant camera loop endpoint and a live dashboard
at the --serve index.
- An update chip appears when a newer release exists. No self-updating.
- Motion throughout, with reduce_motion and an automatic degrade on slow
frames. Labels, roles and focus order on all of the new chrome.
- The application id is io.hookecho.HookEcho, and every screenshot in the
README, the store listings and this repo was reshot on the new chrome.

Rolling build of main — rebuilt and re-published on every push, so this
is always the newest code. Older releases are kept as drafts.
