Summary of Behavior

Spark is a Tinder-style dating-app mockup scoped to a phone-width column (max 420px). It presents three pages wired to a bottom nav: Discover, Matches, and Profile. All data comes from a USER object and a MOCK_MATCHES array hard-coded in the <script> block — the comment "DATA from JSON" is aspirational rather than literal; there is no fetch anywhere.

• Discover — a swipe stack with a front card (Jay, 27, ✓ Verified) and a static back card (Alex, 25). The front card is draggable via mouse and touch, with rotation following the drag distance and a LIKE / NOPE label that fades in as the card tips. Passing ±90px commits a swipe; otherwise it springs back. Three buttons below (Skip ✕, Like ♥, Super Like ★) do the same thing programmatically.
• Nearby / New / Popular tabs sit above the stack and swap highlight styles, firing a toast like "Showing nearby profiles."
• Matches — a horizontal scroller of "New Matches" bubbles plus a message list with preview, timestamp, and unread dot for each of four mock conversations (Sofia, Priya, Zoe, Nadia). Tapping any bubble or row fires a "coming soon" toast.
• Profile — gradient avatar with a verification checkmark, Jay's name/age, a "Member since" line derived from created_at, an About paragraph, a Details table (age, location, verified, gender, photo count), and interest chips derived from USER.interests with a small emoji dictionary.
• A pill-shaped toast at the top slides in for every action, auto-dismissing after 2.2 s.

Styling is warm-dark with a rose/gold gradient logo, Syne display type, and Lato body text. A fadeUp animation plays on each page switch.

Things That Didn't Work as Expected

• The "JSON" story is a lie at the source — USER and MOCK_MATCHES are both literals in the file. Nothing is fetched and the JSON URL referenced in course materials isn't touched.
• The back card never changes. swipeAction rewrites the front card's content and re-animates it in, but the second card in the DOM stays forever "Alex, 25, Jersey City" — so after one swipe the stack shows two copies of the same profile stacked.
• Photos are listed as 2 uploaded, but the URLs are https://example.com/photo1.jpg — <img> tags never appear anyway; the card uses a gradient + emoji placeholder. The "Photos: 2 uploaded" line on the profile page is therefore meaningless.
• The Nearby/New/Popular tabs don't filter anything. They toggle a highlight class and fire a toast; the profile stack is identical regardless. They also rely on event.target inside switchTab, which is a global reference that breaks if the function is ever called programmatically.
• The top "New Matches" row starts with a "You" bubble showing Jay himself, which is confusing in a list whose label implies other people who matched with you.
• Super Like uses the same toast flow as Like — there's no star counter, no limit, and no visual differentiation beyond the upward slide animation.
• The bell and settings buttons in the top nav are pure placeholders; every tap fires "No new notifications" / "Settings coming soon."
• There is no real chat screen. Every "message" row leads to the same toast.
• The swipe threshold is a fixed 90px regardless of viewport width; on very narrow screens the card has to travel most of its width before committing.

Prompt to Improve the App

Make Spark an honest, functional dating-app mock driven by a real JSON payload instead of inline literals, and fix the cosmetic shortcuts that break once the user actually interacts. Specifically:

1. Replace the inline USER and MOCK_MATCHES with a single fetch of a JSON file shaped as { me, deck: [...profiles], matches: [...conversations] }. Keep a sample JSON in the repo so the default experience still works.
2. Build the swipe stack from deck: render the next card into the back slot ahead of time and promote back → front on each swipe (DOM swap, not content rewrite) so the "Alex, 25" ghost no longer repeats.
3. Make the Nearby / New / Popular tabs actually filter the deck by a profile field (distance, createdAt, likeCount), and drop the event.target reliance by taking the button element as an argument.
4. Add a real chat screen: clicking a conversation opens a modal that loads conversation.messages[] and lets you type (stored in memory only is fine for a mock).
5. Show either photos[].url in an actual <img> with a lazy gradient fallback, or remove "Photos: 2 uploaded" from the Details table so the UI stops claiming something it doesn't render.
6. Replace the first "You" bubble with an "Add new match" CTA (or just remove it) so the row matches its label.
7. Give Super Like its own consequence: a limited daily counter shown near the button, an upward animation that lands on a separate "⭐ Super Likes" row on the Matches page, and a different toast with the remaining count.
8. Make swipe-commit distance relative to card width (card.offsetWidth * 0.25) so narrow viewports feel right.
9. Wire the bell and gear to small modals — notifications list, settings (dark/light toggle, distance range) — instead of dead toasts.
10. Keep the existing aesthetic: rose/gold gradient logo, Syne display type, phone-width column, and the current toast/fadeUp animations.
