Steal this idea: a Christmas gift planner

Create a Christmas gift planner section. Write every text on screen in English. The screen is a list of the people the user is buying for, each with their gift ideas. There is no limit to the number of people. When the list is empty, it shows a single card with the line "Who are you shopping for this year?" and an "Add a person" button, and no other add button. As soon as one person exists, that card disappears and a full-width "Add a person" button sits above the list. Adding a person asks for a name and, optionally, a budget — a plain number, shown with the € symbol. The name is whatever the user types: a first name, "Mum", "the neighbours". Each person is a card. Its header shows the name with a small pen icon right next to it, and the number of gifts on the right ("1 gift", "3 gifts"). Tapping anywhere on the header except the pen folds or unfolds the card; folded, only the header shows, and each card remembers whether it is folded. The pen opens "Edit person": name, budget, Save and Cancel side by side, and below them a full-width "Delete person" button that asks first, then removes the person and all their gifts. Unfolded, a card shows the money line, then the gifts, then "Add a gift idea". The money line reads "No gift ideas yet" when the person has no gift, "€45 of €60" with a thin bar when a budget is set, and "€18 spent" when there is no budget. When the total passes the budget, the bar fills completely and the figure turns to "€72 of €60" in a warning colour — never stop counting at the budget. Each gift is one line: its name, its price if there is one, a state button, and "Edit" and "Delete" links. Tapping the state button moves it from "Idea" to "Bought" to "Wrapped", and a wrapped gift goes back to "Idea". Only those three states, always in that order. Bought and wrapped gifts count toward the person's total and the overall total; ideas don't. Wrapping a gift never takes it out of any total. When a gift with no price becomes "Bought", its edit window opens with the cursor already in the price field, labelled "Price paid". "Add a gift idea" asks for a line of text and an optional price. "Edit" lets the user rename the gift, change its price, or move it to another person with a "For whom?" choice. "Delete" asks first. At the top of the screen, three compact cards in a bento layout. A full-width card reads "48 days until Christmas Eve", counting to 24 December; on 24 December it reads "It's Christmas Eve". Below it, two cards side by side: "Progress", a ring that fills with the share of people who are done, with "2/3" in its centre and "done" under it; and "Total spent on gifts", the sum of the prices of every bought or wrapped gift. A person is done as soon as at least one of their gifts is bought or wrapped. No sentence under the ring. Under the add button, when it is true, one line reads "2 people have no gift ideas yet" ("1 person has no gift ideas yet" in the singular); tapping it scrolls to the first of them and unfolds their card. Everything lives on this device alone. The list is never sent anywhere, never shared with anyone, and never visible to us. Say so on the screen, once, in small text at the bottom: "This list stays on your phone. We can't see it." Above that line, a "Lock this list" button lets the user choose a four-digit code, typed twice, and warns in one sentence that a forgotten code cannot be recovered. Every code entry in the section uses four separate boxes: the cursor moves to the next box as each digit is typed, and backspace moves back. Once a code is set, the section asks for it before showing anything. The lock screen offers "Forget the code and erase the list" as the only way out: its confirmation appears on top of the lock screen, and confirming erases the people, the gifts and the code, and shows the empty list. Once unlocked, the button reads "Remove the lock" and asks for the code before removing it. From 26 December, the top of the screen offers "Start next year's list", which keeps the people and their budgets and removes every gift. Nothing is deleted without asking, and every confirmation is a window drawn by the section, on top of everything else. Nothing flickers or flashes: a gift changing state updates in place without the list jumping or scrolling, totals recount without animating, there is no reload effect when the screen opens, and entrance animations play only on first load. Match the app's design.
