Module system_keyboard 

The system’s own keyboard for a text box (ticket 3003): a console’s, or Steam’s on-screen one on the Steam Deck. A screen asks for it through Ctx::system_keyboard, the platform’s App opens it (shuyi_platform::TextInput), and the player’s answer comes back in a later frame. Where the platform has none, a screen reads typed keys (FrameInput::text) or spells on a letter grid, as before.

The handshake, one frame at a time:

1. before each frame the platform says whether it has a keyboard (set_present);
2. a screen asks;
3. after the frame the platform takes the ask (take_ask) and opens its keyboard;
4. once the player closes it, the platform hands back the answer (answer) before a frame, and the screen takes it (take_answer).
