The matrix-seeding edit from the previous commit added a second
`const destNames = engine.destNames || [];` inside rebuildMatrixGrid
while the same name was already declared earlier in the function body.
Chrome threw SyntaxError at parse time, which in turn prevented
a-app.js from wiring window.__nisps at all, which is what made the
earlier FaustWorkletProcessor error look like the root cause — it
was just the next thing that broke once the parse error let partial
modules load.
Verified end-to-end in headless Chromium via Playwright: engine
switches to modular, paramCount=32, audioCtx running, worklet node
live, zero console errors.
Also updates the Modular engine card description to reflect the new
default (32 params = 4 ADSR × 4 + 8 LFO × 2, matrix cells opt-in).
