⚡️ Reminder for JS devs:
When using fetch, don’t forget that the promise only rejects on network errors, not on HTTP errors.
Always check response.ok before parsing the body, otherwise you may call .json() on a 500 HTTP error.

Tip: Scheduling time-based local notifications on Android can be trickier than it looks:
- Exact alarms often need special user-granted permissions
- Android offers multiple APIs for scheduling
- Doze mode throttles timers when the device is idle
- Some OEMs impose additional custom limits

As a non-native English speaker, I sometimes find quina.app by @collinsworth.dev a bit tricky — so I built a small Node.js script to help with my guesses.
Instead of thinking like a human, the script guesses random words filtered from the initial list to narrow things down.

Fiz um game no @nucleo.jor.br no estilo forca no qual a pessoa tem 5 tentativas para adivinhar qual é o termo relacionado à internet a partir de uma dica. Não é fácil, mas tampouco é impossível. Testem e me tragam feedback, pra eu ir melhorando o game.
