Module build 

Scene construction helpers.

Re-exports the sim-value builders and adds a few common scene node shapes plus a reserved-key guard. The guard turns the kind footgun into an immediate, clear failure: kind is the scene-node tag, so a plain data map must not carry a kind key (use a different field name). data_map debug-asserts that.

Constants

RESERVED_DATA_KEYS

Keys reserved for scene-node structure; plain data maps must not use them.

Functions

badge

A scene/badge node. Status carries a text token, never color alone.

box_

A scene/box node with a role and children.

data_map

Build a plain data map, asserting (in debug) that it carries no reserved scene-node key.

float

An f64-domain number value with a canonical literal.

int

An i64-domain number value.

list

A list value.

map

A map value from string-keyed entries (keys become unqualified symbols).

stack

A scene/stack node with a direction and children.

sym

An unqualified symbol value: Expr::Symbol(Symbol::new(name)).

text

A string value.

text_node

A scene/text node.

vector

A vector value.
