What

Adds NFC_bridge to the NFC/RFID section.

Description

NFC_bridge is a single-file, offline tool that converts MIFARE Classic dumps
both ways between Flipper Zero .nfc and Chameleon Ultra .json formats. It
runs entirely client-side in the browser — no server, no build step, no upload.

It solves a common pain point when moving credentials between the two devices:
hand-conversion often leaves a card declared as 1K wrapped in a 4K-sized data
structure with leftover garbage blocks, which readers activate but then reject
during sector authentication. NFC_bridge writes only the blocks that belong to
the declared card type (64 for 1K, 256 for 4K) and drops anything beyond that,
so the output is always internally consistent.

Supports MIFARE Classic 1K and 4K.
