# Persistence. This is a REAL light-wallet-server: it maintains a per-account
# output store and a reorg-safe chain cursor, so it NEEDS a database. Postgres is
# the default for scale; SQLite works for single-operator deployments (enable the
# `sqlite` feature and point DATABASE_URL at a file). Runtime queries only (no
# compile-time `query!` macros) so the crate builds without a live DB.

# View-only Grin rangeproof rewind — recognize a wallet's outputs from its
# `rewind_hash` alone (no spend key). `grin_secp256k1zkp` is Grin's OWN published
# crate (their fork of libsecp256k1-zkp) providing the C bulletproof rewind — we
# depend on it, we do not republish it. `blake2` computes the v3 rewind nonce.
# See src/rewind.rs. (C-FFI: the build host needs a C compiler.)
