Small Door practice
What catches: a Folio should share enough structure that another hand can trust it immediately, but not so much that the Workshop develops a visual house style by accident.
Working distinction: shared language is not shared appearance. Re-entry, custody, limits, current/history, questions, and roads home are semantic obligations. Color, typography, density, motion, metaphor, rhythm, and spatial composition belong to the maker unless the held work itself constrains them.
What must stay true: personality cannot obscure source strength, ownership/custody, current state, or how to get back. Style may surprise; state must not.
