Haggle Bazaar

Build "Haggle Bazaar" — a polished mobile-first portrait web app for the Eazo community.

CONCEPT
A bazaar merchant sells you treasures (a "genuine" ancient compass, a self-warming teapot, a carpet with trust issues) and the price is ALWAYS negotiable. Drag the golden offer-slider to your price: the merchant’s face is a live emotional instrument — eyebrows arch, mustache trembles, feigned heartbreak at lowball offers, theatrical fainting at insults. Find the hidden acceptable band without pushing them into (dramatic, temporary) despair.

RULES & STATES
- 8 embedded items per run, each with a hidden fair-price band and a merchant patience meter (3 rejections per item).
- The merchant’s face morphs continuously with slider position — the real gameplay is reading micro-expressions to sense the band.
- Deals close with a handshake burst and haggle-score (how deep below asking you landed); failures end in a dramatic curtain of disappointment.
- Reveal: "Bazaar Ledger" card — items won, total saved vs asking, merchant’s final respect level, and a haggler title (Tourist to Legend of the Souk).

OPENING
Open with a full-bleed cover artwork unique to this app, drawn procedurally in code: a sun-drenched market stall draped in patterned fabrics and hanging brass lamps, a merchant with magnificent eyebrows mid-gesture behind mounds of spices, the title embroidered on the stall’s awning. Give the title a contrasting outline or glow so it never dissolves into the background, and keep its center above 20% screen height from the top edge is NOT required — instead keep it clear of the top-right corner (language toggle lives there). Below the artwork: at most ONE short tutorial line, then exactly ONE text button that starts play. The button must sit fully above the bottom 88px of the viewport.

GLOBAL REQUIREMENTS
- Language: ship a lightweight built-in i18n layer with exactly two locales, English (en) and Chinese (zh). The app ALWAYS opens in English — never auto-detect or follow the system/browser language. Provide one small, comfortably tappable EN / 中文 toggle placed top-right, about 56px down from the top edge, clear of the device status bar. Chinese appears only after the user actively switches. All share output stays English regardless of locale. Never mix two languages on one screen.
- Fully self-contained: absolutely no external APIs of any kind — no AI calls, no third-party data, media or font services, no remote backend, no login. Embed all data and content in the app code.
- Real Share to the Eazo Community: on the result screen add a real Share button. Compose the result card as an image on a canvas and share it through the Eazo SDK community share (share.compose with the image attachment plus a short English text). Read the resolved { accepted } value: only when accepted is true may the button say "Sent to Eazo"; when accepted is false the button must read "Open in the Eazo app to share"; on error keep the original button. Never claim the post was shared on the plain web. Keep a Replay button next to Share.
- Mobile-first portrait, touch-only, no hover dependence. The app root must follow the host container height (position: fixed; inset: 0; height: 100%) — never 100dvh or 100svh. Size any canvas from its PARENT element using a ResizeObserver (run the fit once on mount), and convert every touch event through getBoundingClientRect() read at event time — never cache the rect and never use window.innerWidth/innerHeight for canvas sizing.
- Safe areas: keep all top UI at least 56px from the top edge. Keep every core interactive control (start button, submit, share, play controls) fully above the bottom 88px of the viewport — the Eazo mobile app overlays a native toolbar there that your code cannot detect.
- No background music and no autoplay audio.
- Complete real states: loading, empty, success, error where relevant. Every control must actually work — no alerts, console-log placeholders or fake results.
- Visual bar: rich, generous visual feedback on every touch (motion, particles, deformation, color, light) while keeping exactly ONE core rule understood within 3 seconds. Canvas 2D preferred for effects; do not use the canvas roundRect API (older iOS Safari lacks it). Never hardcode light text colors onto possibly-light backgrounds — derive text color from the theme.
