Overview

Renders one DiagramElement as a 3-compartment UML class box, matching EA's drawing convention:

┌─────────────────────────┐
│ «Stereotype»            │  ← header (stereotype + name)
│ qualified::Name         │
├─────────────────────────┤
│ + attr1: Type [0..1]    │  ← attributes
│ + attr2: Type [0..*]    │
├─────────────────────────┤
│ + op1(arg: T): T        │  ← operations
└─────────────────────────┘

The stored element bounds are honored as the outer rectangle; internal layout (header / attrs / ops heights) is computed proportionally based on line count.
