Item 1 — VERB LAW: one verb, READ (never SCAN), + a lint that enforces it

The product argued with itself: FAB/nav said "Scan", Free tier "5 scans",
ticker "MLB slate scanned" — while the Ledger says "MY READS". Swept every
user-visible surface to READ:
- BottomTabBar FAB + Nav link: 'Scan' → 'Read'
- Pricing free tier: '5 scans to try the model' → '5 reads …'
- StatStrip: 'Awaiting next scan' → 'Awaiting next read'
- Ticker badge + snapshotService event: tag 'SCAN' → 'READ',
  'slate scanned' → 'slate read' (readSportOf parses BOTH old and new so
  cached ticker items dedupe cleanly through the rollover)
- upgradePitch: 'You've scanned N parlays' / 'unlimited scans' → read/reads

Internal untouched (not user-visible): /api/scan routes, scan_count column,
scanning state, DemoScan/ScanIcon, scanlines CSS, the transitional SCAN
color-map key.

tests/unit/verbLaw.test.js is the enforcement: it fails on user-visible
scan/scanned/scans copy across web/src + src/services (skips comments). Suite
270/3254 green, web build exit 0.
