Simulate and draft edit

On the financial breakdown you can change any editable input and watch the impact on margin and net profit before anything is saved. There are two kinds of change:

• Draft edit (blue +) — a real change you intend to apply, like a new COGS or voucher.
• Simulation (purple +) — a what-if preview that's never saved, like "what if I drop the price 10%?".

How to use it

1. Open a product's financial breakdown.
2. Click the + on a row — blue to stage a real edit, purple to simulate — and enter the new value.
3. The table switches to compare mode: Original → Preview → Diff, so you see the effect on margin and net profit right away.
4. Stack as many edits and simulations as you like; remove any by hovering its bullet and clicking the ✕.
5. Click Apply changes to write your blue edits back to the product. Purple simulations are previews only and are discarded.
