 **Use npm, not bun/pnpm/yarn/Deno.** Not a style preference. Node native modules are rebuilt against Electron's ABI by electron-builder + `@electron/rebuild`, which resolve the tree through `package-lock.json`. Another package manager writes a different lockfile, so that rebuild breaks. `packageManager` + `engines` in `package.json` pin the versions; CI installs with `npm ci`. Note what this does *not* cover: the standalone Swift (macOS) and C++ (Windows) capture helpers are separate executables, built by `npm run build:native:<platform>` and only *copied* into the package as `extraResources` — `build:win` even passes `--config.npmRebuild=false`. Nothing in a normal build compiles them.

 - **Native capture is platform-fragile**: macOS uses ScreenCaptureKit (Swift), Windows uses WGC (C++/Win32). CI runs on Linux only — manual smoke test on real macOS/Windows is required for native changes.
 - **Pixi.js v8** is the rendering engine. Filters come from `pixi-filters` and `@pixi/filter-drop-shadow`. GSAP + `motion` for animation.
-- **i18n**: 13 locales in `src/i18n/locales/<locale>/` (e.g. `src/i18n/locales/en/settings.json`). The `i18n:check` script validates them — run it after touching translation files.

 - **Build pipeline**: `npm run build` is full electron-builder. For iterating on renderer only, use `npm run build-vite` (Vite + tsc, no packaging).
 - **Product constraints**: the project is free forever and explicitly "not production-grade". Don't add paywalls, premium tiers, or logic that gates a feature on who the user is, and don't add upsell language to the README or UI copy. This is a hard constraint, not a judgement call. (A flag that hides an unfinished capture backend is fine — it gates on readiness, not on the user.)
