## PR-02 — PBS Prelude: Add SAFE builtins for Color / ButtonState / Pad / Touch (bounded)
### Goal
Expose hardware types to PBS scripts as **value structs** using `bounded` (no `u16`).
### Required PBS definitions (in prelude / hardware module)
> Put these in the standard library surface that PBS sees without user creating them.
```pbs
pub declare struct Color(value: bounded)
[
(r: int, g: int, b: int): (0b) as rgb
{
...
}
]
[[
BLACK: (...) {}
WHITE: (...) {}
RED: (...) {}
GREEN: (...) {}
BLUE: (...) {}
MAGENTA: (...) {}
TRANSPARENT: (...) {}
COLOR_KEY: (...) {}
]]
{
pub fn raw(self: Color): bounded;
}
pub declare struct ButtonState(
pressed: bool,
released: bool,
down: bool,
hold_frames: bounded
)
pub declare struct Pad(
up: ButtonState,
down: ButtonState,
left: ButtonState,
right: ButtonState,
a: ButtonState,
b: ButtonState,
x: ButtonState,
y: ButtonState,
l: ButtonState,
r: ButtonState,
start: ButtonState,
select: ButtonState
)
{
pub fn any(self: Pad): bool;
}
pub declare struct Touch(
f: ButtonState,
x: int,
y: int
)
```
### Semantics / constraints
* `Color.value` stores the hardware RGB565 *raw* as `bounded`.
* `hold_frames` is `bounded`.
* `x/y` remain `int`.
### Implementation notes (binding)
* `Color.rgb(r,g,b)` must clamp inputs to 0..255 and then pack to RGB565.
* `Color.raw()` returns the internal bounded.
* `Pad.any()` must be a **pure SAFE** function compiled normally (no hostcall).
### Tests (mandatory)
* FE/typecheck: `Color.WHITE` is a `Color`.
* FE/typecheck: `Gfx.clear(Color.WHITE)` typechecks.
* FE/typecheck: `let p: Pad = Input.pad(); if p.any() { }` typechecks.
### Non-goals
* No heap types
* No gates
