Build to a Quality Floor
SHOULD: Demonstrate meticulous craftsmanship: consistent spacing scale (4/8/12/16/24px), pixel-perfect alignment, harmonious proportions. No arbitrary values, misaligned elements, or inconsistent padding. Every detail should feel intentional.
Hold a non-negotiable baseline of responsiveness, focus, and reduced motion, and critique your own work as you build

Why it matters
The floor is invisible when present and unmistakable when missing: consistent spacing rhythm, honest alignment, a focus ring you can actually see, a layout that survives 375px, motion that stands down when asked. It is not a feature to advertise — it is the price of entry. The self-critique half matters as much: look at the rendered thing, not the code. Upstream adds Chanel's rule — before leaving the house, take one accessory off.
