// swift-tools-version:6.3
import PackageDescription

/// Platforms WITHOUT native Combine (`#if canImport(Combine)` is false there, so the
/// sources fall back to `import OpenCombine` — see JSPromise.swift, #11/#15).
/// Must list EVERY non-Apple platform PackageDescription 6.3 exposes, not just .wasi:
/// dropping one (e.g. .linux) would silently unlink OpenCombine for its consumers and
/// break their builds.  (.freebsd exists in the 6.3 swiftinterface but is gated
/// @available(_PackageDescription 999.0) and therefore not usable yet.)
/// On Apple platforms the condition keeps OpenCombine out of the build graph entirely:
/// it is still FETCHED at dependency-resolution time, but never compiled or linked.
