Pack → account → journal line or invoice

Every figure is a door. Click the board number, drop to the account, then to the journal lines or invoice records behind it. Nothing is a black box.

• ✓Tier by tier Each level drills to the next, all the way to the journal line or invoice record that built it.
• ✓No "trust me" When a director asks "where did that come from?", you show them, live, in seconds.
• ✓Audit-ready The trail from pack to source is always there, so audit prep stops being a scramble.
