## Menu sounds

The menus' sound effects (Gyan's ask 2026-11-04: "nice sound effects on selections and everything"): `move` (the
selection moves — a vehicle, a tile, a menu option), `select` (PLAY, Chalo ▶), `back` (Wapas, Esc, Resume), `toggle`
(a switch, the 🔊 chip) and `whoosh` (the garage card / pause menu coming up) on the landing, the garage card and the
pause menu (`src/game/menuSfx.js`). All are CC0 sounds from Freesound — only cut, faded and levelled. Fetched only
after the player's first click / tap / key.

Licence checked on each sound's Freesound page (all show "Creative Commons 0") — or a CC0 pack's own licence file
(Kenney.nl, OpenGameArt.org) — when the A/B set was
made (design/…-ab/README.txt; the A/B sets are local only, never shipped).

**Edits made** (`sox` + `lame`, from each sound's Freesound HQ preview MP3 or the CC0 pack's own file; no pitch
shift; at most a gentle high- / low-pass, noted per file in the A/B README): each one cut tight to its onset (a 1–2 ms fade-in), a short fade-out, levelled so the set sits together, 44.1 kHz; the
short clicks are 16-bit WAV (MP3 padding would delay them), the longer ones 128 kbps MP3.
