func Catalog

func Catalog() []Profile

func ProfileByID

func ProfileByID(profileID string) (Profile, bool)

ProfileByID looks up a profile by exact ID. Returns (profile, true) when found, (zero, false) when the ID is not in the catalog. Unlike the internal profileByID, it does not fall back to a default; the caller decides what to do on miss.

func SelectProfile

func SelectProfile(engine string, region string) Profile

SelectProfile returns a deterministic profile for the given engine and region. It respects lane_profile_ids overrides and falls back to the OS-preferred default. Used by tests and single-instance callers; internally delegates to SelectProfileForSession with empty salt.

func SelectProfileForSession

func SelectProfileForSession(engine, region, salt string) Profile

SelectProfileForSession picks a profile for (engine, region, salt). If a lane_profile_ids override exists it is always honoured. Empty salt picks the first eligible profile (same as SelectProfile). Non-empty salt uses weighted selection seeded by FNV-1a hash of salt, giving each session a stable but varied profile.

type Viewport

type Viewport struct {
	Width  int `json:"width"`
	Height int `json:"height"`
}
