/**
 * Node shape types for Kanban diagrams.
 *
 * **IMPORTANT:** Only some shapes are actually parseable from Mermaid syntax.
 * The JISON lexer only has tokens for these delimiter pairs:
 *
 * | Shape    | Delimiters | Parseable |
 * |----------|------------|-----------|
 * | ROUND    | `()`       | Yes       |
 * | SQUARE   | `[]`       | Yes       |
 * | DIAMOND  | `{{}}`     | Yes       |
 * | STADIUM  | `(())`     | Yes       |
 * | SUBROUTINE | `([-])` | **No** - can render but not parse |
 * | ASYMMETRIC | `(-)-)` | **No** - can render but not parse |
 * | Others   | N/A        | **No** - enum values exist but unsupported |
 *
 * The non-parseable shapes exist in the enum (inherited from mermaid.js flowchart)
 * but the Kanban JISON grammar doesn't have lexer tokens for them.
 * You can create nodes with these types programmatically and render them,
 * but parsing the rendered output will fail.
 *
 * This is a limitation in mermaid.js's Kanban grammar, not this library.
