Build a Band uses the actual BeepBox synthesizer with new LearnPlay UI and
original tunes. This is a simplified activity, not the complete BeepBox editor.

LearnPlay changes: compile-csp.mjs precompiles the two DSP factories required
by our fixed chip/noise instrument presets. beepbox-csp.js replaces runtime
new Function calls with the precompiled functions; no unsafe-eval CSP permission
is required. Unsupported instrument/effect combinations throw explicitly.
Reproduce: node compile-csp.mjs. Test: node verify-csp.mjs (from this directory).
Original source is in the included beepbox-4.2.0.tgz archive and synth/*.ts;
readable upstream compiled source is global/beepbox_synth.js.

No third-party network, accounts, telemetry, sharing or samples are included.
Original package notices and MIT license are preserved. No sampled recordings.
