Web NFC isn't exposed in Capacitor's WebView, so the APK needs a native writer.
Adds packages/skatespots-nfc — a local Capacitor Android plugin (Kotlin,
enableReaderMode + NDEF URL record), registered BY NAME (not bundled). lib/nfc.ts
now uses the plugin on native and Web NFC on the web. iOS can't write tags.
⚠️ UNVERIFIED (needs cap sync + a device). README documents it.
- lib/nfc.ts: isNfcSupported() + writeNfcUrl() via Web NFC (Chrome/Android),
writing ONLY the verify URL (the same pointer the QR carries).
- NfcWriteButton component (renders nothing where Web NFC is unavailable — iOS,
desktop, Capacitor WebView — so there's no dead button).
- Wired into: the venue's issued-pass list (issuer copies a tag per holder), the
organiser's issued list, and the holder's 'My passes' view (+ Print).
- i18n nfc.* EN/ES. Tags are passive and clonable like a QR; trust still comes
from the relay signature, and /verify already handles taps.
