9633 in hex is 25a1

please fix

and next time add to your checklist - i have checked that dec and hex values match

[opensyria]

Thank you for catching the hex mismatch!

I've pushed a fix:

• Incorrect: 0x80002599
• Correct: 0x800025A1

Verification:

9633 (decimal) = 0x25A1 (hex)
0x80000000 + 0x25A1 = 0x800025A1 ✓

I've also updated the PR description with:

• Clear conversion verification
• A new checklist item confirming decimal/hex validation

Appreciate the thorough review — this will help ensure accuracy in future submissions.
