Kill the Icon-Tile Feature Card
NEVER: Stack a rounded-square icon tile above a feature heading — the tell is geometric: a heading's previous sibling measuring 32–128px on both axes, roughly square, with a visible background or border and a border-radius under half its width. Move the icon inline into the heading line, drop the container, or give the feature a real image. (A circular avatar, radius = half the width, is exempt.)
Stop stacking a rounded-square tinted icon tile above every feature heading — put the icon inline instead

Why it matters
The tell is geometric, so it can be detected mechanically: a previous sibling of a heading that measures 32–128px on BOTH axes, is roughly square, has a visible background or border, and has a border-radius under half its width. (A circular avatar is exempt — its radius is half the width.) That is the shape every generator reaches for, and it is why three-up feature grids from different products are indistinguishable.
Break the geometry, not the icon: move the icon inline into the heading line, drop the container entirely, or let the feature carry an actual image. If the icon must sit in a box, the box has to earn it.
