Chart Prompts

Restyle my chart in the "Showroom Night" 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: an evening in a high-end furniture showroom. Deep espresso darkness, warm brass light pooling in the middle, soft vignette corners and an elegant wide-tracked all-caps headline.

Colors (use these exact values):
- Background: #1E1712 (espresso), with a centered radial glow of #C9A46A at 7% opacity fading to 0 and a vignette from transparent (at 55% of the radius) to #000000 at 55% opacity in the corners.
- Primary series and highlights: #C9A46A (warm brass). Secondary series: #EDE3D1 (ivory).
- Secondary text and axes: #9C8C7A. Gridlines: #3A2F26.

Typography (Google Fonts):
- Tenor Sans for all text. Eyebrow 11.5px uppercase with 4px letter-spacing in #9C8C7A; title 19.5px uppercase with 3.4px letter-spacing in #EDE3D1, centered; a 60px 1px brass rule under it; subtitle 13.5px #9C8C7A centered; panel labels 12px uppercase with 3px letter-spacing in the series color; axis labels 11.5px; peak labels 13px brass; end totals 14px with an 11px caption.

Layout:
- Centered header block: eyebrow at y 54, title at y 98, rule at y 118, subtitle at y 142.
- Plot from x 96 to 864. When the second series is on a different scale, give it its own short panel under the main one (main panel about y 186 to 390, second panel about y 434 to 510), sharing the x axis. Never use a second y axis.
- End totals sit 14px right of each line's last point. A small brass dot legend and the source line share the bottom row at y 570.

Axes and grid:
- 1px #3A2F26 horizontal gridlines, value labels right-aligned 12px left of the plot, a 1px #9C8C7A baseline at 60% opacity.
- Weekly 5px ticks below the bottom panel, month labels uppercase with 1.6px letter-spacing, and a 1px dotted (2 4) #9C8C7A line at 35% opacity marking the month boundary through both panels.

Marks:
- Line chart: the main series as a 2.2px brass line with straight segments and a brass area fill at 8% opacity; the second series as a thin 1.3px ivory line. Mark recurring peaks (e.g. every Saturday) with a 4.2px brass dot ringed 2px in the background color and the value in brass 12px above.
- Bar chart: slim brass bars (2px radius on the top corners) with the peak bars at full opacity and the rest at 55%, peak values in brass above; any second series as thin ivory ticks or a separate short panel.

Avoid: bright white, saturated colors, heavy glows, dual axes, a boxed legend and bold weights.

When you're done, render the chart and check that the wide-tracked title fits inside the canvas with margin, the vignette never hides labels, every peak dot has a label that does not touch the line, and the stated ratio in the subtitle matches the data.
