   AH5 Office — admin panel
   Designed & Developed by Anwar Hossain — https://anwar.com.bd

   Direction: a working ledger, not a dashboard poster.
   - Ink navy chrome, warm paper workspace
   - Every amount is monospaced and right-aligned so columns read like a book
   - Two semantic colours carry meaning, never decoration:
       teal  = money in / settled
       stamp = money out / overdue
   - Signature: the ledger strip under the header — a cheque-stub band of
     live balances with the Official / Personal book tab cut into it.
