ASCII Diagram Builder

Generate correctly aligned ASCII box diagrams using programmatic helpers rather than hand-counting characters. Hand-drawn ASCII diagrams inevitably have alignment bugs because humans can't reliably count columns across 50+ character lines.

The Font-Rendering Problem

This is invisible at small scales but accumulates over many characters. A ┬ at column 30 in a line of ─ characters will appear visually shifted compared to a │ at column 30 in a line of spaces.

This means:
