v1 fixes Comma at the int64 minimum. v0 negated in int64, and -n on math.MinInt64 is math.MinInt64, so FormatInt emitted its own sign and the neg branch prepended a second: Comma(math.MinInt64) returned --9,223,372,036,854,775,808. The magnitude now goes through uint64. v0 stays resolvable for its existing importers.

Integer-only, on purpose. No floats anywhere: a rendered value that differed between nodes would be a consensus bug, so the single decimal place in Bytes comes from scaling by 10 and taking a remainder.

Durations are in blocks, never seconds. There is no wall clock on chain, so "about 2 hours" is a lie dressed as precision. Blocks says ~1,200 blocks and lets the caller decide what that means on their chain — and rounds deliberately, because false precision is worse than none.

Ordinal handles the teens (11th/12th/13th, not 11st/12nd/13rd) — the case naive implementations get wrong. Truncate counts runes, so multi-byte text is never sliced mid-character.
