// rlmPath.symbol -> \*Token

Register

Register records token under its rlmPath.symbol key and returns that key. Token.ID() carries a trailing sequence id (rlmPath.symbol.\<id>) that keeps token identities/events unique, but the registry deliberately keys by rlmPath.symbol so lookups don't need to know the id, and so a realm cannot register two tokens under the same symbol (overwrite/alias guard).

Transfer

Transfer moves \`amount\` out of the CALLING REALM's own balance. Call it non-crossing, forwarding your own \`cur\`: grc20reg.Transfer(0, cur, "gno.land/r/demo/defi/foo20.FOO", to, 100)

Approve

Approve sets an allowance owned by the CALLING REALM, letting \`spender\` draw on the calling realm's balance. It does not touch the signing user's allowances.

TransferFrom

TransferFrom spends an allowance with the CALLING REALM as the spender. Note the allowance direction this implies: \`from\` must have approved the calling realm, not the signing user. That is the supported way for a realm to move a user's funds — the user grants the realm an allowance, and the realm draws on it as itself, so every debit is one the owner authorized against that specific realm.
