/**

 * Immutable bundle of all per-field metadata computed once per class and cached for reuse across
13 
 * every {@code load()} and {@code export()} call.
14 
 *
15 
 * <p>For repeating fields ({@code count > 1}), {@link #context} is {@code null};
16 
 * {@link #formatInstructions} and {@link #formatter} describe a single <em>element</em>, and
17 
 * {@link #elementType} / {@link #elementContexts} carry the element type and one
18 
 * {@link FormatContext} per element (offsets {@code offset + length * i}). The runtime delegates
19 
 * to {@link RepeatingFieldSupport}.
20 
 * For fields whose type is itself a {@code @Record}, {@link #formatter} is {@code null} and the
21 
 * runtime recurses into {@code FixedFormatManagerImpl}.
