// File: internal/standards/doc.go
//
// Package standards defines weatherfeeder’s provider-agnostic “project law”:
//
//   - Schema identifiers and versioning conventions (see schema.go).
//   - Canonical interpretations / cross-provider mappings that are not specific to a
//     single upstream API (e.g., shared code tables, text heuristics, unit policy).
//   - Wire-format conventions for canonical payloads.
//
// Standards are used by both sources and normalizers. Keep this package free of
// provider-specific logic and free of dependencies on internal/sources/* or
// internal/normalizers/* to avoid import cycles.
//
// Wire-format conventions
// -----------------------
// For readability and stability, canonical payloads (weather.* schemas) should not emit
// noisy floating-point representations. weatherfeeder enforces this by rounding float
// values in canonical payloads to 4 digits after the decimal point at normalization
// finalization time.
//
// Provider-specific decoding helpers and quirks live in internal/providers/<provider>.
// Normalizer implementations and canonical mapping logic live in internal/normalizers/<provider>.
