/**
 * Bounding box of an arc swept from `startAngle` to `endAngle` (gauge degrees,
 * 0 = top, clockwise) on a unit circle centred at the origin, using the same
 * angle convention as `getPointOnCircle` (x = sin θ, y = -cos θ).
 *
 * Evaluates the two endpoints plus every cardinal direction (top/right/bottom/
 * left) that falls inside the swept range, since the extrema of the arc can
 * only occur at endpoints or where it crosses an axis. Returns fractions of the
 * radius so callers can fit the gauge into an arbitrary box.
