Prompt for your coding agent

Paste it with your chart's code. It restyles your data to match this chart.

Restyle my chart in the "Soda Fountain" style described below. Keep my data, chart type, title meaning and units; change only the presentation. Use the charting library this project already uses (plain SVG if there is none). If the library can't express a detail, draw it in a custom layer instead of dropping it. Measurements assume a 960 x 600 chart; scale them proportionally.

Mood: a 1950s soda-shop menu board or bottler's sales sheet. Cheerful, sugary and tidy: a candy red awning over a creamy page, one bold red line and a little price bubble, but disciplined enough for a real report.

Colors (use these exact values):
- Page: #FBF3E4 (cream) for the whole canvas.
- Candy red: #C8202F for the header band, the data line, star marker outlines, the baseline, the peak callout and the footer stripe.
- Mint accent: #4FA89E, used only for the price bubble and its trailing fizz circles.
- Ink: #3B2420 (cocoa) for subtitle, category labels and ordinary callouts. Secondary text #8A6A5C. Gridlines #E6D3BA.
- Star marker fill: #FFFFFF.

Typography (Google Fonts):
- Lobster Two 700 italic for the title (40px, cream on the red band, sentence case, stating the finding) and for the big numeral inside the price bubble (40px, cream).
- Oswald for everything else: subtitle 18px 400 cocoa stating measure, unit and period; axis values 14px #8A6A5C; category labels 15px 500 cocoa; value callouts 15 to 17px 600; small caps labels (band tag, bubble words, footer brand) 11 to 13px 500 to 600 uppercase with 2.5 to 3px letter-spacing.

Layout:
- A full-width red header band 86px tall whose bottom edge is a row of downward scallops (semicircles of radius 12, every 24px), with a row of 2px cream dots centered in each scallop just above the edge. The title sits on the band 52px from the left, baseline y 58; a small uppercase tag ("SODA FOUNTAIN REPORT") is right-aligned on the band in cream at 90% opacity.
- Subtitle on the cream page at y 146, 56px from the left.
- Plot from x 100 to 892, y 196 to 496, with points inset 24px from each end.
- Footer at y 560: "Source: ..." left in 12px #8A6A5C, a spaced-out uppercase brand line right-aligned.
- A candy stripe runs full width under the footer from y 578 to 588: 45-degree stripes, 9px red and 9px cream, edged top and bottom with 1px red hairlines.

Axes and grid:
- No y-axis line. Four dotted gridlines, 1.2px #E6D3BA, 2 on 5 off with round caps. Y values right-aligned 14px left of the plot.
- A 2.5px red baseline at zero. Category labels 28px below it.

Marks:
- Line chart: straight segments, 6px candy red, round joins and caps, over a red area fill at 7% opacity down to the baseline. Each point is a five-pointed star (outer radius 10, inner 4.4), filled #FFFFFF with a 2.2px red outline. Label the first point (15px 600 cocoa) and the peak ("134,000 cases", 17px 600 red) 20 to 22px above the star.
- Bar chart: square-cornered candy red bars about 55% of the band, each capped with a small white star (radius 8, red outline) centered on its top edge; the same red area-free look, value labels in Oswald 600 above the bars and the peak value in red.
- Price bubble: a mint circle of radius 48 floating in empty space near the peak (upper left of it, clear of the line), with a 1.5px dashed cream ring at radius 42 (3 on 4 off) and a 1.5px mint outer ring at radius 54. Inside: "ONLY" (Oswald 600 12px, 3px letter-spacing), a big Lobster Two numeral, and "CENTS" below. Three hollow mint circles (radius 8, 5.5, 3.5, 1.8px stroke) trail up and to the right like soda fizz.

Avoid: gradients, drop shadows, more than one line color, a boxed legend, emoji, and letting the bubble or its fizz touch the line or a label.

When you're done, render the chart and check that the scallops tile evenly across the full width, the stars are crisp white with red outlines at every point, the bubble sits in clear space, and the candy stripe runs edge to edge under the footer.
