Video Hook Reviewer — illustrative example

INPUT
Opening spends 40 seconds greeting viewers before showing a simple formula fix.

RESULT
Start with the broken formula and the result to expect, then introduce only the context needed to follow the fix.

REVIEW
Evaluate the first seconds against the video's actual promise. A dramatic opening that delays or misrepresents the lesson can create the wrong expectation.

This is a teaching example, not a live execution record.
