// errors — domain-agnostic error types. Mirrors ref/hare/errors/.
//
// Named-void tagged-union variants, so `(T | errors.invalid | ...)`
// composes with every other module's error surface at the tag level.
// Per-domain errors (io.eof, io.closed, io.underread, strconv.overflow,
// ...) live in their own modules; this module ships only the generic
// conditions Hare's errors:: exports.
//
// Subset shipped today; add more from Hare's errors/common.ha as callers
// need them.
