0. NO Firebase imports at all.
|
||||
|
||||
1. Export *exactly* the same function names the UI already uses.
|
||||
|
||||
2. Provide no-op or mock implementations that fulfil those contracts.
|
||||
|
||||
3. Tiny in-memory cache (+ localStorage) so screens have something
|
||||
|
||||
to display and don’t blow up on undefined values.
