/**
 * Parse a chain id as returned by an EIP-1193 provider (e.g. `eth_chainId`).
 *
 * EIP-695 specifies a hex-encoded quantity such as `0x343b`, but providers are
 * inconsistent and may return a decimal string or a number instead. `Number()`
 * handles all three.
 *
 * Do NOT reach for `parseInt(value, 10)` here: it silently returns 0 for hex
 * input, which reads as "wrong network" for every chain. Use this helper so the
 * radix decision lives in one tested place rather than at each call site.
 *
 * Returns `null` when the value cannot be parsed, so callers can tell an
 * unknown chain apart from a legitimately parsed id.
