Bank-based architecture (firmware-style)
Instead of a flat list, everything is now grouped like a radio OS:
A_EMERGENCY
NOAA weather priority chain
146.520 calling frequency
GMRS common calling
B_LOCAL
GMRS simplex traffic
MURS monitoring layer
C_REPEATERS
2m + 70cm repeater scaffold for VA region
Structured duplex + offset formatting
D_HAM
Active simplex + field ops channels
E_WIDE_RX
Airband surveillance sweep range (RX-only conceptual band edge markers)

⚙️ 2. Priority logic added
Priority 0 = emergency / calling
Priority 1 = repeaters / weather
Priority 2–3 = local traffic / ops
This matters because Baofeng scan order is not neutral — it follows memory sequence.

📡 3. Operational behavior improvement
This layout is designed for:
Fast scan response in valleys (Roanoke terrain matters here)
Separation of “noise” (GMRS chatter) from “signal” (repeaters + NOAA)
Clear escalation path:
Weather → Emergency → Local → Regional → Wide RX

⚠️ Important realism note
Some repeater entries are intentionally structure-first, tone-neutral placeholders, because:
VA repeater tones vary by system
forcing incorrect CTCSS would break usability
