Chart Prompts

Restyle my chart in the "Train Length" 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 railroad technical operating bulletin. A white sheet with a thin rust border, a bulletin number in the header, a boxed instruction and a single ramp of rust that deepens toward the values that matter.

Colors (use these exact values):
- Page: #FFFFFF. A 1.5px #9A3412 border inset 16px from every edge.
- Main ramp: from #F1C6A8 (pale rust) for the lowest bins to #9A3412 (rust) for the last bin before the limit, interpolated evenly.
- Over-limit bins: #5C1D0A (dark rust), on a #FBF1EA tint panel behind the over-limit zone.
- Ink: #1C1917. Secondary text: #6B625C. Gridlines: #ECE6E1.

Typography (Google Fonts):
- Bitter 700 29px for the title (sentence case, stating the finding with its number), Bitter 400 13px for the instruction text.
- Barlow Condensed for everything else: bulletin number 700 15px uppercase with 2px letter-spacing in #9A3412; header right side 500 14px uppercase with 1.4px letter-spacing in #6B625C; subtitle 400 18px; axis labels 500 15px; axis titles 600 12.5 to 13px uppercase with 1.4 to 2px letter-spacing; value labels 600 14px.

Layout:
- 48px inner margins. Header line: "OPERATING BULLETIN No. 26-114" left, railroad, department and period right, then a 1px rust rule.
- Title and subtitle (measure, bin size and total count) under the header, then the plot from x 96 to 904 and y 196 to 488.
- An instruction box in the empty upper-left of the plot: white fill, 1px rust stroke, a 4px solid rust bar on its left edge, "INSTRUCTION 7(b)" in 700 13px rust, then two lines of Bitter 13px ink.
- Footer: "Source: ..." left and "SUPERSEDES BULLETIN No. ..." right, both inside the border.

Axes and grid:
- Horizontal 1px #ECE6E1 gridlines; y labels 500 15px #6B625C right-aligned with a small "TRAINS" unit label above. Leave headroom above the tallest bar for the instruction box.
- A 1.5px #1C1917 baseline with 6px ticks every 1,000 units and comma-separated labels, and a centered uppercase axis title below.

Marks:
- Bar chart (histogram): touching bins with a 3px gap, square corners, colored by the ramp; bins past the limit in #5C1D0A with their counts printed 7px above them in 600 14px #5C1D0A. Draw the limit as a 1.6px #1C1917 vertical line dashed 7 4, from above the plot to the baseline, labelled "SIDING LIMIT 10,000 FT" in 700 14px with a two-line #5C1D0A note of the count and share over the limit.
- Line chart: a 2.5px #9A3412 line (a frequency polygon or trend) with a pale #F1C6A8 area under it, the stretch past the limit drawn in #5C1D0A over the #FBF1EA tint, and the same dashed limit line and labels.

Avoid: rounded bars, gradients inside a bar, drop shadows, extra hues beyond the rust family, and gridlines drawn over the bars.

When you're done, render the chart and check that the ramp gets darker toward the limit, every bin past the limit is dark rust, the share in the title equals the over-limit count divided by the total, and the instruction box covers no bars.
