 * render only the decimals actually present, up to 6: capping at 2 rounded
 * `196.867461` *up* to `196.87`, so Max filled a value above the real balance
 * and tripped the insufficient-balance guard. At 6 decimals the value is
 * reproduced exactly. There is no minimum, so trailing zeros are trimmed —
 * a `1.1` balance fills as `1.1`, not `1.100000` (or `1.10`).
 *
 * Not `formatCurrencyAndStringify` — that helper produces a 2-decimal `$`
 * display string, while this fills the editable input with an exact,
 * re-parsable pUSD amount.
