# #024 Calendar parent-cell FIT v1.0.219

Status: Candidate / NOT COMPLETED.

- Amount controls use official frozen #029 `inheritParent:true`. The **table cell** is the size / background / border owner, not the child NumberBox.
- Parent cell rectangle (both width and height) is passed to official `BoneNumberBox.setOptions` after mount and on parent `ResizeObserver`.
- Child outer border, rounding, spacing removed; inactive grid fills parent; clicking switches to edit, blur restores voucher view.
- Payroll earnings and deductions, bank net amount, ledger debit and credit amounts.
- Integer yen only for new amounts; preserve legacy fraction data (no silent rounding).
- Test actual parent/child geometry at multiple widths AND row heights. Parent FIT cannot be claimed by changing only digit count.
- User Windows / localhost / SQLite persistence not verified. Frozen #029 and #048 source unchanged.
