`app.security.__csp_notes` failed `tauri.conf.json` schema validation
("Additional properties are not allowed") on BOTH platforms before any
compile. JSON can't hold comments and Tauri forbids extra keys, so the
rationale lives here instead:
CSP rationale (audit 2026-07): tightened from the fully-open policy.
- 'unsafe-eval' MUST stay: the native→web bridge (forward_deeplink /
emit_to_web) uses window.eval, governed by page CSP; also covers crypto wasm.
- The sha256 hash allowlists the single inline `window.global ||= window;`
shim in cinny's index.html (~line 96). If that snippet or its indentation
changes, recompute the hash or the shim is silently blocked.
- connect-src / img-src / media-src keep http: (plain-http homeservers).
- Review-added: Google Fonts (VT323) + OpenStreetMap iframe (m.location).
- style-src keeps 'unsafe-inline' for React style attributes.
