Struct CapsDecision 

struct CapsDecision {
    fullcolor: bool,
    downgraded_color: bool,
    too_large: Option<(i32, i32)>,
}

The chroma format and dimensional feasibility a session settles on given the driver’s reported capabilities, so init degrades cleanly instead of failing opaquely.

• fullcolor is the chroma actually used: 4:4:4 only when it was requested and the GPU carries it, otherwise 4:2:0.
• downgraded_color records that a 4:4:4 request was met with 4:2:0, so the caller says so once.
• too_large carries the driver’s (max_w, max_h) when the requested geometry exceeds it; the caller then declines NVENC and falls back to software rather than failing to initialize.

A capability that could not be queried is None and does not gate: 4:4:4 stays as requested and the dimension test is skipped, so an unavailable answer never forces a false downgrade or refusal.
