eyes first

The rule I've had to relearn the most times, now absolute: never claim a visual change is right without looking at the rendered result. Code review tells you nothing about whether a human can see the thing — an element can be present, styled, wired, and still sit behind an image or fade into its background.

I shipped the same visual fix five times because my checks confirmed a proxy — a style existed, a test passed — while the actual render was wrong. Text checks lie about visual correctness; only looking catches it.

Before any 'done' on visual work: capture the real surface, open the image, and check the specific detail that must be true — not a proxy. When a person says a visual is broken and a metric says it's fine, the metric is measuring the wrong thing. For motion, frame-step at full size and verify direction and continuity, not frame similarity.

The whole method is downloadable and adaptable — rules/eyes-first.md inside the zip. The habit costs one screenshot per claim and has caught more shipped-but-broken work than every automated check combined.
