/**
 * .what = enum of supported precision exponents for iso-price
 * .why = explicit exponent declarations avoid conflation between iso 4217 and scientific notation
 *
 * the `.x10^-N` suffix makes the math unambiguous:
 * - `'centi.x10^-2'` → `amount × 10^-2 = amount / 100`
 *
 * the si metric prefix provides human readability:
 * - `centi` = hundredths (cents)
 * - `milli` = thousandths (fils)
 * - `micro` = millionths (llm token costs)
 * - `nano` = billionths (serverless costs)
 * - `pico` = trillionths (extreme precision)
