/*******
 * Serialize a style object into a CSS declaration list string.
 *
 * Purpose:
 * - Converts an internal `StyleObject` (dictionary of properties → values)
 *   into a browser-compatible declaration list suitable for `style=""`
 *   or for emitting inline styles.
 *
 * Output format:
 * - Uses `kebab-case` property names for non-custom properties.
 * - Preserves custom properties (`--foo`) verbatim as keys.
 * - Produces declarations in a deterministic order (sorted by final key).
 * - Produces a compact string with:
 *   - one space after `:`
 *   - declarations separated by `"; "`
 *   - no trailing semicolon at the end
 *
 * Normalization:
 * - Skips null/undefined values.
 * - Trims stringified values.
 * - Skips empty values after trimming.
 * - Strips any trailing semicolons from values to avoid `;;` output.
 *
 * Nested rule maps are not inline declarations and are rejected.
 *
 * @param style - Style object mapping property names to values (or undefined).
 * @returns A CSS declaration list string, or `""` when there is nothing to emit.
