+ * Variables consumed:
+ *   string  $name         — select name attribute (also used for id)
+ *   string  $label        — visible label text
+ *   array   $options      — each element must have 'id' and 'name' keys;
+ *                           may optionally have 'code' for display suffix
+ *   mixed   $selected     — currently selected value (compared to option 'id');
+ *                           pass null or '' for no selection
+ *   bool    $required     — whether the field is required; default false
+ *   string  $placeholder  — text for the leading empty <option>; default ''
+ *                           set to null to suppress the empty option entirely
+ *   string|null $id       — override the id attribute (defaults to $name)
+ *   string|null $hint     — optional hint shown in <small> below the select
