The version being built is clearly marked. Everything else is archived or deleted

No competing versions of the same block are left on the ready-for-dev page

Screens are laid out left to right in the order of the flow

Every distance comes from the spacing scale — no arbitrary values

Every value is a whole number

Distances are set as auto-layout gaps, not by where the layer sits on the canvas

No section has a fixed height — height comes from the content

Line height is a number everywhere. Auto is not used

Text layers hug their content. None has been stretched by hand

Vertical trim is left on standard

Kicker, heading and paragraph sit in one auto layout with an explicit gap
