Chart Prompts

Restyle my chart in the "Soil Profile" 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 plate from a soil survey field guide. Columns of real soil colors hanging below a ground line, labeled like a pedologist's notebook, with a calm serif and precise figures.

Colors (use these exact values):
- Page: #F4EFE6 (light warm clay).
- Ink: #2E241C for titles, ground line and boundary ticks; #7B6E60 for secondary text and depth figures; gridlines #E2D8C8; grass tufts #6E7F4E.
- Categories (soil horizons, top to bottom): #3F2B1D (dark humus brown), #D8C29D (pale clay), #A9522B (rust), #7E5638 (medium brown), #8E9B86 (gray-green parent material). Labels inside dark segments are #F4EFE6; inside the pale and gray-green segments, #2E241C.

Typography (Google Fonts):
- Crimson Pro for the title (600, 29px, stating the finding), subtitle (italic 17px #7B6E60), column names (600, 15px), segment codes (600 italic 15px) and legend text (600 16px names, italic 14px descriptions).
- Karla for figures and small labels: eyebrow 11.5px 600 uppercase with 2px letter-spacing, depth axis 12px, boundary depths 11px (the last one in each column 700 #2E241C), column numbers 11px 600 with 1px letter-spacing, source 11.5px.

Layout:
- 56px side margins; eyebrow, title and subtitle at the top.
- The chart takes the left 600px; a 1px #E2D8C8 vertical rule, then a field-guide legend ("HORIZON KEY") on the right with one 30 x 40 px color chip per category, its code centered on the chip, a name and a one-line italic description.
- Source line at the bottom left.

Axes and grid:
- The value axis runs downward from a 1.6px #2E241C ground line at zero. Depth labels on the left every 50 units, the unit ("cm") under the last one. Gridlines 0.8px #E2D8C8 dashed 3 on 3.
- Each column carries a small uppercase number and a serif name above the ground line, and small grass tufts (1.2px #6E7F4E strokes) standing on the line.

Marks:
- Bar chart: vertical stacked bars 46px wide, hanging down from the ground line, one segment per category in its color, square corners, no gaps. Codes centered in any segment at least 18px tall. At each lower boundary a 5px #2E241C tick to the right of the bar and the depth figure 8px beyond it. The bottom of each bar ends in a 1px zigzag to show where the pit stops. The Bt segments carry a faint mottled dot texture and the C segments a gravel dot texture (small dots at 18 to 22% opacity).
- Line chart: draw each series as a step line hanging from the same ground line, the area between steps filled with the category colors at full strength, boundary depths printed at each step and the same legend on the right.

Avoid: rounded bars, gradients, bright or synthetic colors, a boxed legend inside the plot, and upward-growing bars for depth data.

When you're done, render the chart and check that depth runs downward, every boundary figure matches the data and sits clear of its neighbors, the pale segments keep dark labels, and the title's comparison is arithmetically true.
