Vencord plugin for the Discord desktop app. Toggles fire on key press, push-to-talk infers releases GNOME drops (re-registration probe), and GNOME's trigger descriptions are matched correctly. Includes basis-path tests, a patch checker against the live Discord bundle, the design spec and the README assets.

// unique find, one match per replacement, patched module still parses.
|

// Usage: node check-patches.mjs [dir with discord.com/assets/*.js, optional lazy/ subdir]
|
|
// Without a dir it downloads the entry bundles that discord.com/app serves right now.
