Chart Prompts

Restyle my chart in the "Age Bands" 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 page from an official population register. Cream paper, double-ruled running head, a framed total in the corner and a quiet sage histogram where one group of bars is singled out by a dark green outline and a bracket.

Colors (use these exact values):
- Page: #FCF8EF (cream).
- Highlighted group fill: #8FA88A (dusty sage). Other bars: #B7C7B2 (light sage).
- Highlight outline, bracket, eyebrow and total box: #3F5E3A (dark green).
- Ink: #2B2A24. Secondary text: #6F6A5C. Gridlines and foot rule: #DCD4C3.

Typography (Google Fonts):
- Crimson Text 700 for the title (29px, sentence case, states the finding); Crimson Text 600 at 40px with lining figures for the boxed total; Crimson Text italic 13 to 14px for small notes ("enumerated residents", "Bar labels in thousands", the page folio).
- Nunito Sans for everything else: eyebrow 11px 700 uppercase, 1.8px letter-spacing, dark green; subtitle 15px #6F6A5C; axis labels 12.5px with tabular figures; category labels 12px 600 ink; value labels 11.5px (700 dark green on highlighted bars, 600 #6F6A5C elsewhere); bracket label 14px 800 dark green; group labels 12.5px 700; source 12px.

Layout:
- 56px side margins. Running head at top left with a double rule under it (1.2px ink, then 0.5px ink 3px lower), ending before the total box.
- Total box top right, 188 x 104 px: a 1.4px dark green frame with a 0.5px inner frame inset 4px; inside, a small uppercase "TOTAL POPULATION", the big serif figure and an italic caption.
- Plot from x 104 to 904, y 196 to 470. Under the axis, group labels ("Under 15", "15 to 64", "65 and over") centered under 1px rules that span each group, with each group's share.

Axes and grid:
- Horizontal gridlines 1px #DCD4C3 at round steps (1,000 persons); y labels right-aligned, comma-separated. A 1.4px ink baseline. No vertical gridlines.

Marks:
- Bar chart: a histogram. Bars touch edge to edge (no gaps), separated only by a 0.8px cream stroke. Highlighted bands are #8FA88A with a 1.6px #3F5E3A outline inset 1px; other bands are #B7C7B2 with no outline. Value labels centered 7px above each bar. A 1.4px dark green bracket spans the highlighted bands about 34px above the tallest bar, with 9px down-ticks at each end and a gap in the middle for its label ("Working age 15-64: 64.2%").
- Line chart: a 2.5px #3F5E3A line over a #B7C7B2 area fill, with the highlighted range of the x axis shaded behind in #8FA88A at 35% opacity and the same bracket and label above it.

Avoid: gaps between histogram bars, rounded corners, gradients, shadows, bright colors, and outlining bars outside the highlighted group.

When you're done, render the chart and check that the bracket's share equals the highlighted bands' sum divided by the total, the group shares add to 100 within rounding, and the title does not run into the total box.
