Companion build 0.5.27 (versionCode 47) shims navigator.clipboard natively, so
in-app copy/paste is fixed with zero web changes — but the contract must not be
clobbered (no unconditional re-define, no Object.freeze).
Still open web-side: main.ts's fake readText() makes SendBitcoinModal's Paste
button render and silently no-op in plain-HTTP browsers; 30 writeText call
sites across three inconsistent patterns, ~10 of which toast 'Copied!'
regardless of success; scanner prewarm/torch/constraints/no-reinit.
Also records three factual corrections to docs/qr-scanner-snappiness-handover.md
(ZXing not ML Kit; FORMAT_QR_CODE + KEEP_ONLY_LATEST already in place; do NOT
drop to 720p — 1080p is a deliberate 0.5.22 fix for dense bolt11 QRs).
Routed at Phase 11: the signed-PSBT paste affordance and the scanner items are
the same surface as WALLET-05.
