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.

 ### 4. TallyFlow Capture
-Automated data capture system for fixed and high-volume scanning environments.
+Mobile photo documentation linked to barcodes, RFID, jobs/orders, and categories (formerly PhotoTag). iOS + Android apps with web review.
 
 **Key Capabilities:**
-- Fixed RFID reader integration for continuous asset movement detection
-- Gateway and edge processing for real-time data collection
-- High-throughput receiving and shipping workflows
-- Exception flagging and automated alerts
-- Seamless handoff to TallyFlow Core for record updates
+- Capture photos tied to scanned IDs and categories
+- Offline-friendly capture with later upload (categories cacheable; GPS fallback when address lookup fails)
+- Library / detail review; full-resolution viewing
+- **Public share collections** (web) for controlled external photo access
+- Android: barcode symbology selection in Settings; highlight scanned barcodes
+- Integrates with Core for tagged photo visibility where deployed
 
 ### 5. TallyFlow Edge
-Connectivity layer for sensors, gateways, and connected devices. Runs as an always-on Windows or Linux service.
+Site edge service for fixed and remote RFID/barcode readers. Runs as an always-on Windows or Linux service (repo `tallyflow-iot`).
 
 **Key Capabilities:**
-- Real-time location tracking via Edge gateways and beacons
-- Environmental sensor data (temperature, humidity, shock) linked to assets
-- Automated status updates without manual scanning
-- Edge-to-cloud data pipelines feeding TallyFlow Core
-- Support for both short-range (BLE, RFID) and wide-area (LoRa, cellular) IoT networks
-- RFID GPIO support for reader triggers and control
-- Endpoint configuration available for Edge and Mobile readers
-- ERP integration via keyboard wedge, database integration, and spreadsheet output
-- Optional custom receiving or shipping user interface that integrates with an ERP system
-- Compatible with TallyFlow Core deployed in the cloud or on-premises
+- Multi-reader management (e.g. Impinj, Zebra fixed readers; ATID ATF862 Master mode where supported)
+- Unified tag stream with ops UI (start/stop, health, statistics)
+- **Remote reader API** for handhelds — used by **TallyFlow Scout**
+- Reader-side filtering (site-specific; validate before promising)
+- Egress: CSV/spreadsheet, REST, AMQP → TallyFlow Core
+- Keyboard wedge (+ optional lookup) into focused ERP/apps
+- MCP read tools for AI copilots (health/readers/recent tags — not autonomous dock control by default)
+- Compatible with Core in cloud or on-premises, or standalone without Core
+
+### 6. TallyFlow Scout
+Handheld Flutter app for **Edge** floors (`tallyflow-assets-iot`). **Does not replace TallyFlow Assets.**
+
+**Three sections:**
+- **Collect** — scan barcode/RFID; submit to Edge as a remote reader, or export CSV offline
+- **Verify** — GS1 barcode vs RFID EPC identity match (SGTIN/SSCC/GRAI/GIAI-style)
+- **Locate** — seek-and-find by EPC/GTIN/part with geiger feedback; works offline without Edge
+
+**Hardware:** Industrial Android scanners (e.g. Janam XR2, ATID, SEUIC, URFID); camera barcode fallback; desktop simulator for demos. EN/ES UI.

 ## Typical Workflows
 
 - **Asset Onboarding:** Print/encode a tag using TallyFlow Print → optionally register in Core.
-- **Field Operations:** Use mobile app to locate assets, update status, or enroll new items.
-- **Automated Receiving/Shipping:** Fixed readers (Capture) detect tagged assets moving through dock doors or checkpoints.
-- **Condition Monitoring:** IoT sensors track environmental data tied to specific assets or shipments.
+- **Field Operations (Core):** Use **Assets** to locate assets, update status, enroll, or scan-and-print.
+- **Field Operations (Edge):** Use **Scout** Collect / Verify / Locate with Edge remote reader or offline CSV/locate.
+- **Automated Receiving/Shipping:** Fixed readers via **Edge** detect tagged assets at docks/tunnels; Scout can add handheld reads to the same site feed.
 - **Bulk Operations:** Import large numbers of assets via Excel.
 - **Compliance & Traceability:** Use category, zone, tag, and Edge data for reporting and audit trails (e.g., FSMA 204 food traceability scenarios).
