A vendor-neutral, local-first feature-flag library for Compose Multiplatform. Type-safe flag declarations (Boolean / Int / String / Enum / Variant), deterministic A/B variant assignment via hashing, optional HTTP remote source, and a built-in `FlagOverrideDrawer` that lets QA toggle flags + variants at runtime. Persistent overrides via multiplatform-settings. Pairs with `debug-bar` — drop in `FlagBarSection(flags)` for an integrated debug tab.
