Get a settled Browser observation

Returns one already-settled, bounded, sanitized Browser observation under its exact Computer and Screen. Raw provider coordinates, screenshot bytes, form values, hidden sensitive fields, browser chrome, and unrelated targets cannot fit the response. A mismatched resource path is not addressable, and an admission that has not settled remains absent.

Checkfu support posture: alpha; hosted. No release evidence journey applies to this operation.
