## [0.1.0] - unreleased

### Added
- Initial release: on-device **NFC** for Mob apps. (MOB-16)
  - **Read** NDEF messages — `MobNfc.start_reading/2` / `stop_reading/1` open a
    reader session; NDEF and tag events arrive as `{:nfc, ...}` messages.
    `MobNfc.available?/0` reports radio presence + enabled state.
  - **Raw tag UIDs** — `start_reading/2` with `mode: :tag` reads a tag's UID/tech
    without NDEF (iOS `NFCTagReaderSession`).
  - **Write** NDEF — `MobNfc.write_ndef/3` writes an NDEF message to a tag.
  - **Card emulation (HCE)** — `MobNfc.emulate_ndef/3` / `stop_emulation/1`
    emulate an NDEF tag (read-only or `:writable`) via Android `HostApduService`.
    **Android only** (iOS has no third-party HCE; it replies `:unsupported`).
  - iOS `CoreNFC`; Android `NfcAdapter` reader mode + HCE. NDEF parse/encode and
    Text/URI helpers in `MobNfc.Ndef`.
