Binary ⇄ Decimal ⇄ Hexadecimal — fast, offline, phone‑friendly.

You can include optional prefix 0x.
Spaces and underscores are allowed for readability (e.g., 1010_0101).
Supports negatives. No fractional values.

Mechanics: we parse the edited field → normalize → convert using exact integer math (no floats) → update the other fields. If input is invalid, we highlight only that field and leave the others unchanged.
