Create one finished 9:16 vertical Chinese fuel-price graphic poster. Flat artwork filling the canvas, no mockup. Art direction: a roadside petrol-station PRICE SIGN translated into a contemporary Swiss graphic-design print. NOT a newspaper, NOT a dashboard, NOT a vintage receipt. The four fuel grades and their prices are the entire visual subject. A crisp modular composition, confident typographic scale, distinctive asymmetrical alignment and controlled empty space. No slogans, no illustration of a fuel nozzle, no photographs, no unnecessary decoration.

Palette: smooth warm ivory #F4F1E8 (background), rich charcoal #18201B (text), vivid vermilion #E34A2B (one main price band), one very small pale citron #DDE56C detail. No grain, no grunge, no gradients, no shadows, no rounded cards. Modern Chinese sans-serif throughout, prices use beautifully drawn bold condensed sans-serif numerals, no serif numerals. Strong typographic precision, identical decimal positioning, generous margins. Designed, not a default template.

Layout contract:
TOP 0–16%: a small citron horizontal rectangle at upper left followed by medium-bold title "广东油价". Date "2026.11.04" sits aligned upper right. Beneath, a short small subtitle "成品油最高零售价". Restrained header, not giant text. A small dark horizontal rule only where it supports alignment.
MAIN 16–43%: one full-width vermilion band inside the outer safe margins. It is the unmistakable centre of attention. In warm ivory text, left side has grade "92" in large bold numerals and directly below the smaller word "汽油". Right side has the larger, bolder price "8.91", with "元/升" below aligned to the right. Grade and price share a clear baseline. Huge typography but with ample internal padding. No boxes inside this band, no repetition of this price elsewhere.
SECOND 43–66%: on the ivory page, a similarly aligned open typographic row. Left grade "95" with "汽油" below. Right price "9.65" with "元/升" below. All in charcoal. Slightly less visual weight than the main red band. This row is not enclosed in a card. Enough breathing room between red band and black numbers.
THIRD 66–82%: two equal side-by-side compact data columns separated by a single thin vertical rule. Left column has label "89号汽油" and beneath the price "8.27" followed by smaller "元/升". Right column has label "0号柴油" and beneath the price "8.60" followed by smaller "元/升". Large clear prices, both columns aligned, equal internal spacing. A single thin horizontal rule below closes the data area.
FOOTER 82–100%: clear, well-spaced small type in dark charcoal, not microtext. Exact lines: "2026年10月29日24时起执行" / "数据来源：广东省发展改革委" / "以上为最高零售价，实际以加油站为准". Keep generous bottom margin. No other text.

Accuracy is mandatory. All visible copy is precisely the quoted Chinese strings and numbers above. The data pairings are exactly 92汽油=8.91, 95汽油=9.65, 89号汽油=8.27, 0号柴油=8.60, all in 元/升. Do not invent 98-grade data or forecasts. No English, no logo, no QR code, no extra tagline, no duplicated labels or missing decimal points. Distinguish fuel grade numerals from price numerals clearly. Sharp simplified Chinese. All text entirely inside safe margins. Result should feel like a graphic designer's bold, functional public-information poster, not a generic app UI.
