- README: rewrite Build section for the hand-written Makefile (make /
make DEBUG=1 / run / test / bench). Add a "System dependencies" table
with the X11+GL dev packages per distro (apt/dnf/pacman/zypper/apk),
since a clone won't build without them and the error is otherwise
cryptic. Fix stale ./bin/Debug paths to ./bin/Release.
- Makefile: add `make check-deps` — probes for the required X11/GL dev
headers and prints the install command for the detected distro on
failure (via /etc/os-release).
- build_web.sh: auto-discover app modules from src/*.c (drop the
hardcoded APP_MODULES list that had to be hand-synced), matching the
desktop Makefile. Excludes the desktop platform backends. Remove the
stale rspektrum.make reference.

Commit the accumulated working-tree changes as one snapshot.
- Headless render: `--render OUT.png INPUT.wav` draws the spectrogram
(full window, or `--pane` for the spectrogram pane only) to a PNG
with no visible window. Options: `--annotations`/`--no-annotations`,
`--annotation-opacity`, `--width`/`--height`.
- mLnL annotations: parse the optional `mLnL` RIFF chunk (schema v2)
and render tx_frame/assertion/control overlays, a timeline lane, and
a waveform-scope echo, with hover tooltips on the spectrogram,
timeline, and scope.
- sched_offset_ms: parse the per-frame intent->air latency and surface
it in the hover tooltips (boxes stay air-anchored upstream).
- Supporting: build wiring (rspektrum.make), shared types/headers,
web-build and capture-script tweaks, and removal of the old
synchrosqueezing LaTeX doc.

Make the Emscripten build behave like the desktop app for loading, window
scaling, and exporting. All changes are #ifdef __EMSCRIPTEN__-gated or no-op on
desktop, so native behavior is unchanged.
Scaling:
- Drop FLAG_WINDOW_HIGHDPI on web. The emscripten-GLFW shim forces a fixed
pixel canvas style (!important) when HiDPI-aware, overriding the shell's
100vw/100vh CSS so the canvas can't fill the page; raylib's own resize/window
callbacks also disagree about dividing by devicePixelRatio, desyncing the
framebuffer from the reported screen size.
- Sync raylib's window size to window.innerWidth/innerHeight each frame via
SetWindowSize (guarded against no-op churn). This keeps screen size, GL
viewport, and projection consistent, so the UI fills the viewport and reflows
on resize like the desktop window.
Loading:
- Compute the full-resolution STFT synchronously when a file loads instead of
the desktop overview-then-deferred-high-res path, which relied on many
main-loop iterations yielding to the browser and appeared to stall partway.
- Allow the wasm heap to grow (INITIAL_MEMORY + ALLOW_MEMORY_GROWTH) so longer
recordings fit now that everything is computed up front.
Exports:
- Add Platform_OfferFileToUser(): no-op on desktop (file is already on disk);
on web it reads the just-written file from MEMFS and triggers a browser
download, then unlinks the temp copy. Wired into PNG and WAV export, which
now show just the filename in the status message.

The web build had bit-rotted since the last successful build (Apr 12):
- build_web.sh only compiled spectrogram.c + platform_web.c, but commit
3a8f20b split the code into 9 modules — link failed with undefined
symbols. Now compiles all app modules (kept in sync with rspektrum.make,
swapping platform_linux -> platform_web).
- Dropped -DPLATFORM_WEB from the app-module compile/link: the platform
refactor (b6942d8) added a `Platform` enum whose PLATFORM_WEB enumerator
collides with the macro. Web behavior is selected by linking
platform_web.c, not the macro, so the define was never needed by our code
(raylib still gets it in its own build).
- Removed the stale `fonts/DejaVuSansMono.ttf` preload (font moved to
resources/fonts/); resources@resources already bundles it and the runtime
loads it relative to the resources dir.
- platform_web.c: include <errno.h> for ENOSYS (this stub had never compiled).
- build_web.sh: skip the slow raylib rebuild when libraylib.a already exists.
Verified: `./build_web.sh release` exits 0 and produces html/js/wasm/data;
font is packaged; all artifacts serve 200 via python http.server and the
wasm has valid magic bytes.

Move all Unix-specific syscalls (fork, execvp, waitpid, strerror, /tmp)
into a platform layer so the same spectrogram.c can target Windows
(CreateProcess) and WebAssembly (stubs). Key changes:
- src/platform.h: public API with spawn handle, error codes, path helpers
- src/platform_linux.c: fork/execvp implementation, /tmp, strerror
- src/platform_win32.c: CreateProcess implementation, temp dir lookup
- src/platform_web.c: stub implementations (no subprocess support on web)
- src/spectrogram.c: consume only platform.h; replace pid_t/fork/execvp
with Platform_SpawnChild/WaitForChild; use Platform_GetTempDir() for
/tmp path; replace strdup with malloc/memcpy for portability
- Build: add platform_*.c to gmake, Premake, and build_web.sh
- Add incremental STFT processing with loading overlay and progress bar
- Add auto-scaling amplitude (max dB, max-40dB floor) for low-signal files
- Replace fixed bitmap text with TTF font scaled by window size for crisp rendering at any resolution
- Fix command-line file path resolution relative to original working directory
- Scale file browser dialog dimensions by GetUIScale() to prevent text overlap
- Disable ESC key closing the window
- Fix FFT size changes to restart STFT computation
