Defined in:

Overview

Emits the shape <g> for a Package element: a rectangular body polygon plus a "tab" polygon on top. EA renders every Package as this folder-like silhouette regardless of diagram type.

Layout (element bounds cover tab + body together):

┌───┐
│tab│   ← top TAB_HEIGHT_SINGLE rows ABOVE element bounds;
│   │     when a stereotype is present, the tab grows to
└───┴──────────┐  TAB_HEIGHT_DOUBLE rows and extends INTO
│               │   the bounds; the name renders bold,
│     body      │   left-aligned. The body always starts
│               │   where the tab ends.
└───────────────┘
