/**
 * Serialize a CSS-property record to an inline-style declaration string
 * (`prop1: val1; prop2: val2`). Properties are alphabetised so the
 * output is deterministic across runs.
 *
 * - Empty record returns `''`.
 * - Empty-string values are skipped (treat as "unset").
 * - Values containing `;` are dropped — they would terminate the
 *   declaration early and risk attribute-injection in `style="…"`
 *   contexts. Callers should pre-escape user data; this is a
 *   defensive last line.
 *
 * The returned string is suitable for direct interpolation into an
 * HTML `style="…"` attribute *after* the usual attribute-value HTML
 * escaping (no `&` / `"` injection here — this only guards against
 * stray semicolons).
