Tree guides reference

TTreeGuideKind enumerates the glyph sets used by Tree to draw branches: the vertical "continue" line, the fork at sibling positions, the L-shape at the last child, and the horizontal arm.

Available kinds

Kind	Glyphs
Ascii	|, +, `, - (always ASCII).
Line (default)	─ │ ├ └
Heavy	━ ┃ ┣ ┗
Double	═ ║ ╠ ╚
Bold	Alias for Heavy.

Non-unicode terminals automatically fall back to Ascii, regardless of the configured kind.

Glyph parts

TTreeGuidePart:

Part	Used for
Space	Empty depth slot (when an ancestor is the last child).
Continue	Vertical line at a depth where an ancestor isn't the last child.
Fork	Branch at a node that has more siblings below.
Last	Branch at the last child of its parent.
Horizontal	The horizontal arm before the node label.

Usage

tree := Widgets.Tree('root').WithGuide(TTreeGuideKind.Heavy);

Get an ITreeGuide instance directly:

guide := Widgets.TreeGuide(TTreeGuideKind.Double);

Custom guides

Implement ITreeGuide to ship a custom glyph set. Your impl returns a Char per TTreeGuidePart plus the kind.
