Struct Capabilities 

pub struct Capabilities {
    pub can_quit: bool,
}

Static feature-flag struct describing what the host environment supports. Each platform impl exposes a CAPABILITIES constant of this type. UI / input code reads it to gate affordances that have no meaning on a given platform — e.g. the [q] quit help-bar hint is hidden in the browser, where the wasm bundle has no authority to close the tab.

Add new fields here when a feature genuinely diverges between surfaces (and add the matching value to both native::CAPABILITIES and web::CAPABILITIES); don’t reach for cfg(target_arch) deeper in the tree if a capability flag fits the seam.

Fields

can_quit: bool

Whether the player can quit the running instance from inside the game. True on native (terminal close = process exit). False on web — the wasm has no authority over the tab; the player closes the page or navigates away themselves.
