A row of frequency bars under the track progress, on by default and
toggleable with the client spectrum config option. Because the audio
plays on the server and clients may be remote, the spectrum is produced
server-side, not captured locally: audio-player taps its own output
into a lock-free ring on the audio thread (one store per sample, no
locks), crabidy-server runs a Hann + realfft over 2048 samples at 20fps,
folds it into log-spaced bars, and broadcasts them as a new SpectrumFrame
on the update stream. The task idles when nothing is playing or no
client is listening. The TUI renders block-glyph bars in the now-playing
pane; the web client renders the same bins as CSS bars.

crabidy-server now serves a browser client with the same functionality
as the TUI at its own address, behind the default-on web-ui feature.
The new cbd-web crate is a client-side Leptos/WASM app talking gRPC-web
(tonic-web-wasm-client) over the same crabidy-core client and proto the
TUI uses, so parity is structural: library browsing, search terms,
marks, bookmarks/captures with live progress and confirmed deletion,
the full queue and playback controls, and the update stream with
reconnect. Keys mirror the TUI; every key also has a clickable control.
Styling is hand-written modern CSS with a single crab orange-red accent
and light/dark themes.
The server wraps its existing gRPC service in tonic-web and composes one
axum router (auth layer -> grpc-web -> service, web bundle as fallback);
axum::serve replaces tonic transport, and native gRPC (h2c) still works.
The bundle is embedded via include_dir behind a build.rs that falls back
to a placeholder so a plain cargo build needs no wasm toolchain. To make
crabidy-core build for wasm, tonic is codegen-only there (transport
generation disabled) and native config loading is target-gated.
devenv gains the wasm toolchain and build-web/serve-web scripts.
