What this verification provides

A successful match between the locally-computed SHA-256 hash and the published reference provides:

Integrity — the page content is bit-for-bit identical to the published reference
Tamper detection — any modification (even a single character) produces a completely different SHA-256 hash
Source consistency — the page you are viewing is the same one published by Https Card — Internet Identity Card Ltd
