A node's color now flows down the lines to its children, mind-map style:
Watering's teal colors the lines to Rain barrel and Drip line. It used to
color the line from the root down to Watering itself, which also left the
shared bus of a parent's branches in whichever child's color was drawn
last. Branches follow their parent by default, and stay dim when the
parent has no color.

The model holds the rules: a document is a tree under one root, with
loose nodes beside it and cross-links between any two nodes. Every change
runs as a transaction that rolls back on error and returns an undo step
(the old and new values of whatever it touched), so undo and redo need no
code of their own per command. Text from outside (titles, tags, names) is
checked once, when it becomes a typed value. Folding (Open, Auto, Closed,
plus focus) is one function that every view will share.
storage::document_file reads and writes `.cum` files in RON, with
multi-line bodies kept readable, `\n` line endings on every OS, and errors
that name the node they're about. The tests cover the tree rules, 500
random edits undone and redone step by step, folding, and the file format
(the example from DESIGN.md is written back character for character).
