Expert JavaScriptBridge helpers for browser API integration (persistence, analytics).

NEVER Do in Web Development

• NEVER use FileAccess for saves — FileAccess.open("user://save.dat") on web? Browser sandbox blocks filesystem. Use JavaScriptBridge + localStorage.
• NEVER forget loading screen — 20MB wasm download with default load screen = user closes tab. MUST customize index.html with progress bar + brand assets.
• NEVER use threads — Thread.new() on web? Not supported. Use await for async OR split work across frames with await get_tree().process_frame.
• NEVER ignore HTTPS requirement — Geolocation, microphone, webcam APIs REQUIRE HTTPS. Local http:// = APIs blocked. Use localhost OR HTTPS.
• NEVER exceed 50MB build size — 100MB WebAssembly = user rage-quits during load. Compress textures (ETC2/ASTC), exclude unused assets.
• NEVER hardcode window size — get_viewport().size = Vector2(1920, 1080) on web? Breaks mobile browsers. Use get_window().size_changed + responsive UI.
