+	 * <ol>
+	 *   <li>A {@code Holder.Reference<Biome>} might be created initially just with a
+	 *       {@link net.minecraft.resources.ResourceKey} (like {@code minecraft:plains}), but its actual
+	 *       {@link net.minecraft.core.Holder#value() value()} (the {@code Biome} object itself) might be {@code null}
+	 *       at construction time.</li>
+	 *   <li>Later, during game loading, registry population, or potentially due to modifications by other mods
+	 *       (e.g., Polytone), the system calls internal binding methods (like {@code bindValue(Biome)})
+	 *       on the {@code Holder} instance. This sets or <strong>updates</strong> the internal reference to the
+	 *       actual {@code Biome} object.</li>
+	 *   <li>Crucially, the binding process might assign a completely <strong>new</strong> {@code Biome} object
+	 *       instance to the {@code Holder} reference, replacing any previous one.</li>
+	 * </ol>
+	 *
+	 * <p>If we unwrapped the {@code Holder} using {@code .value()} within the constructor (the old way),
+	 * our class's internal {@code biome} field would permanently store a reference to whatever {@code Biome}
+	 * object the {@code Holder} pointed to *at that exact moment*. It would have no link back to the
+	 * {@code Holder} and would be unaware if the {@code Holder} was later updated to point to a different
+	 * (or the initially missing) {@code Biome} object. This would lead to using stale or even {@code null} data.</p>
+	 *
+	 * <p>By storing the {@code Holder<Biome>} itself, this class can call {@link net.minecraft.core.Holder#value()}
+	 * whenever the biome information is needed, ensuring it always retrieves the most current {@code Biome}
+	 * instance associated with the holder at that time.</p>
