+ * Formats a number of bytes into a human-readable string using binary units (KiB, MiB, GiB, TiB).
+ *
+ * - For values less than 1024, returns the value in bytes (e.g., "512 B").
+ * - For larger values, converts to the appropriate unit and formats:
+ *   - If the integer part is 1000 or more, shows no decimal (e.g., "1024 KiB").
+ *   - If the decimal part is at least 0.1, shows one decimal place (e.g., 1228.8 KiB formats as "1.2 MiB").
+ *   - Otherwise, shows no decimal (e.g., 1075.2 MiB == 1.05 GiB, formats as "1 GiB").
+ *
+ * @param v - The number of bytes to format.
+ * @returns The formatted string with the appropriate unit.
