docs: TallyFlow Scout marketing + Edge/Print/Capture feature refresh

Review tallyflow-assets-iot (TallyFlow Scout v0.5.3): Collect, Verify,
Locate with Edge remote reader / offline CSV locate. Clarify Scout does
not replace Core Assets. Refresh Edge, Print parent-container and multi-
unit identity notes, Capture share/offline/barcode notes, architecture,
use cases, capabilities, and website drafts after src/ repo pulls.

+# TallyFlow Scout Review (repo: tallyflow-assets-iot)
+
+**Product name:** TallyFlow Scout  
+**Package:** `tallyflow_scout`  
+**Version reviewed:** 0.5.3+10 (master `2c479fb`, July 2026)  
+**Tech stack:** Flutter (Material 3), `flutter_hardware_scanner`, optional camera barcode (ML Kit), HTTP client to Edge  
+
+## Role in platform
+
+Handheld **Collect / Verify / Locate** app for **TallyFlow Edge**.  
+**Not** a replacement for **TallyFlow Assets** (`tallyflow_mobile` → Core).
+
+## Destinations
+
+1. **Collect** (nav key still `navUpdate` in l10n) — scan list, submit to Edge remote reader API or export CSV  
+2. **Verify** — GS1 barcode identity vs RFID EPC encodings (`gs1_verify_match`); optional auto-confirm  
+3. **Locate** — offline seek-and-find / geiger (`locate_screen`, RSSI colors aligned with Assets pick-list palette)
+
+## Integration
+
+- Client: `lib/services/tallyflow_iot_client.dart` → `{baseUrl}/api/v1/health`, `/reader/barcode`, `/reader/rfid`
+- Remote reader must exist on Edge (`type = remote`, enabled); reader name must match Settings
+- Offline: Collect + CSV + Locate without server; banner when Edge unreachable
+
+## Hardware
+
+- Android industrial devices via hardware scanner plugin (XR2, ATID AARs, SEUIC, URFID noted in tree)
+- Camera barcode fallback when no hardware scanner / init failure
+- Desktop: simulator always on
+
+## Notable modules
+
+- `epc_mask.dart`, `sdg_rain_decode.dart` — EPC type / Internal part decode  
+- `scan_csv_exporter.dart` — CSV share/save  
+- `l10n` — English + Spanish  
+- Tests cover EPC mask, GS1 verify match, locate finds, CSV export, symbology filter  
+
+## Marketing guardrails
+
+- Say **Scout works with Edge**; **Assets works with Core**
+- Three sections only: Collect, Verify, Locate  
+- Locate offline is a real differentiator for floor find without Core  
+- Do not claim full asset CRUD, zones, or scan-and-print in Scout
