/**
 * Fully-resolved patch diagram configuration (internal type used by renderer and layout).
 *
 * Users configure this diagram via `mermaid.initialize()` with a `patch` key and/or
 * standard Mermaid `themeVariables`.  Only the following keys are accepted from the user:
 *
 *   background, fontFamily, fontSize, portPlacement, nodePlacementStrategy,
 *   legend, legendPosition
 *
 * Signal colours and node chrome colours are derived from the built-in theme palette
 * (DEFAULT_CONFIG / DARK_CONFIG / NEUTRAL_CONFIG) and can be further adjusted via standard
 * Mermaid themeVariables (primaryColor → nodeBgColor, primaryBorderColor → nodeBandDark,
 * primaryTextColor → nodeNameColor, secondaryTextColor → nodeLabelColor).  They are not
 * settable through the `patch.*` user config.
