The same library as the Lost in Production trailer: 29 semantic names (tap, type, pop, notif, whoosh, register, printer, stamp, tick, bell…) mapped to soundeffect-lab.info files in sfx/sources.json, each with its measured onset so the mixer puts the transient exactly on the beat. The site's terms allow commercial use but not redistributing the files, so they are gitignored and `npm run sfx` downloads them; catalog.json indexes the whole library.

Sound effects
Every sound effect comes from 効果音ラボ, the library the Lost in Production trailer used.
It is free for commercial use with no credit required, but its terms forbid redistributing the files themselves. So public/sfx/*.mp3 is gitignored and fetched on demand.
npm run sfx # → public/sfx/<name>.mp3 (idempotent; refetches a name whose pick changed)
bash sfx/fetch-sfx.sh --force # refetch everything · bash sfx/fetch-sfx.sh tap click → only those
node sfx/measure.mjs --write # after changing a pick: re-measure duration/onset/peak into sources.json
The site serves an mp3 only to a browser User-Agent with a Referer from its own category page. The script sends both, and it fails loudly if the site answers with anything other than an mp3. Entries with a clip are cut out of a longer recording with ffmpeg (the system ffmpeg, else Remotion's bundled one). Every other file is the site's original, byte for byte.
sources.jsonmaps each semantic name to a file and its measuredduration,onset,peakDb,peakAtandaudible.scripts/mix.mjssubtractsonset(the first sample above −40 dBFS) so the transient lands exactly on the cue time. For swells (whoosh, swoosh, register's bell),peakAtis where the loud part is.audibleis how long the sound really rings, which is useful fordur.catalog.jsonlists every mp3 on the site (2,352: 1,375 effects and 977 voice lines). Each entry has its path, Japanese title and description, an English gloss and the page it is listed on. Grep it to pick new sounds. The site's "life" category isvarious(生活).
