nvrl 62dde885aa Tap to listen, drop marks, bar-timed fades and solar flares
The first visit shows a welcome screen where one tap starts a guest
session; sign-in moves below it. Guests see a "sign in" pill, are
asked once to sign in after five likes or a first follow, and need
two taps to forget themselves.

Drops are found in the waveform and marked on it; "drop" and the d
key jump a bar before the next one. Long and dj-mix fades start on a
bar once the beat is locked. Radio sheets can be shared as /?r=handle.

The audio features now follow the bar, gaps before drops and the
wobble rate, and a new flare pass draws loops round the drop on each
kick, with a setting under visuals.

nvrl 2dcca0bc94 Fix the flat drop on Linux and morph its play/pause in one shape
The kick wave in the vertex shader squared a negative number with pow(), which
GLSL leaves undefined. Mesa returns NaN there, so on Linux the drop's position
pinned to the clamp: it stayed a plain round sphere without wobble, and its
normals split it into a dark yin-yang. The squares are written out now, and the
normal comes from the slope of the displacement instead of two whole positions.

The play/pause icon is one shape whose corners move: each pause bar turns into
half of the play triangle, with a small swing in between, instead of two icons
faded over each other. It sits on a disc of frosted artwork with a lit rim, and a
ring round it shows the track's progress, or runs while the track loads, which
replaces the flat spinner. The surface calms down under the icon gradually
instead of jumping flat, a double-tap no longer flickers the icon, and a mouse
resting on the playing drop shows the pause bars faintly.

Also:
- Low-density desktop screens render the drop at twice the resolution.
- Quality steps follow the display's own frame rate and step back up again.
- A lost WebGL context brings the drop back once it is restored.
- A paused drop keeps breathing at a low frame rate on desktop.
- Without Web Audio (iOS) jumps in the waveform count as kicks, so the drop lands on drops there too.
- Artists without an image get their own colour from their name, so their drop no longer sinks into the page.
- z toggles zen mode: just the drop, bigger, and the music.

nvrl b09a7370ca Let the riddim wobble drive the liquid drop and bring back its texture
Two new features follow the bass line itself: its envelope against the last moment,
which rises and falls with every wub, and how open its filter is (spectral centroid
of the bass and mids). Each wub swells the drop, and as the filter opens its surface
crinkles and spikes like before. Every layer keeps a floor, so the drop never goes
still and nothing snaps in from nothing; riddim gets its soft terraces back. Kicks
still make it jump.

nvrl cccdf1d11c Make the liquid drop wobble like jelly and jump on prominent hits
The terraces, snare spikes and fine ripples creased the surface into jagged corners.
The drop now always moves in broad, smooth lobes, and the strongest kick and bass
hits (weighed by prominence against the last seconds) throw it up on a spring: it
stretches as it rises, squashes as it lands and jiggles back. Snares pump its size.
It also swells in from the flat artwork more slowly.

nvrl e8c0f40128 Start drop detection from the first sound and count onsets in the debug overlay
Previews often open inside a drop; the long loudness average now covers no more than
what has been heard, so that is the baseline rather than a drop.

nvrl 856ccb3b9a Replace loudness pulse with onset tracking and add liquid artwork visuals
The bass meter sat at full scale through every dubstep drop, so the glow froze.
features.ts now tracks band levels against their recent range, kick and snare
onsets from spectral flux, wobble in the mids, and drops, and the pulse follows
the kicks.

The playing card's artwork becomes a WebGL2 liquid drop that moves with those
features; tempo, tags and key set its character. Falls back to the plain artwork
without WebGL2, with reduced motion, or with visuals set to simple (v).
?debug=audio shows what the tracker hears.
