Split-the-bill calculator

Use with: build-web-app. Resume line when done: Built {project_name}, a bill-splitting app my friend group uses — live at {url}

Brief

A calculator built for how your friend group splits a bill, not the even-split textbook case. Enter the items, assign them to people, and get a per-person total that handles your group's known cases: the one who only had fries, the shared appetizer, the one who forgot their wallet and owes from last time. One calculation, done completely, with tax and tip distributed the way your group agrees is fair.

Personalize

• The group. Your friends by name, saved so you do not retype them every dinner. Their quirks are the requirements.
• The cases from real bills. Take three receipts from actual outings and make the app produce the numbers your group settled on by hand. Those three become your test cases.
• The tip rule. Proportional to what you ordered, or split evenly? Your group has an opinion. Encode that one.

Milestones

1. Write the three receipt cases in the README with the expected per-person totals before any code.
2. Items in, even split out, deployed. Ugly is fine.
3. Per-item assignment: each item belongs to one or more people, totals update as you assign.
4. Tax and tip distributed by your group's rule; the three receipt cases come out right.
5. Saved people and a designed empty state; a finished split survives a reload so you can show it at the table.
6. Use it at a real meal. Note in the README what broke and what you fixed. Final README.

Done means

• Live URL responding; a split in progress survives a reload
• The three receipt cases from real bills compute correctly
• Rounding never loses or invents a cent; totals sum to the bill
• Used at least once at a real group meal, noted in the README
• At least 10 commits across at least 7 distinct days, authored by you
• SESSIONS.md has an entry per session, written by you
