Chart Prompts

Restyle my chart in the "Numeral Poster" 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 typographic exhibition poster. Off-white stock, one gigantic pale numeral behind everything, a flat slab of cobalt in front and tight small print held in a strict rule system.

Colors (use these exact values):
- Page: #F3F0E8 (off-white poster stock).
- Ink for rules, labels and the first title line: #111111.
- Cobalt for the data fill, the second title line, the latest value and footer column heads: #1F3FBF.
- Deep cobalt for the crisp top edge of the fill: #132A8A.
- Ghost numeral: #CFE2F3 (pale sky), solid, no opacity tricks.
- Secondary text (axis values, footer notes): #6B6B6B.

Typography (Google Fonts):
- Anton (400, the only weight) for the ghost numeral, the title and the latest value label, always uppercase.
- Inter 400/500/600/700 for everything else.
- Ghost numeral: the last two digits of the final year (for example "25"), Anton 500px, -8px letter-spacing, right-aligned so it ends near x 944 with its baseline near y 516. It fills the right half of the canvas and sits behind the chart.
- Title: two lines of Anton 68px, 0.5px letter-spacing, stating the finding; line one in ink, line two in cobalt. Baselines at about y 142 and 212.
- Subtitle: Inter 500 15px ink with measure, unit and period, directly under the title.
- Header strip: Inter 700 11px uppercase, 2.2px letter-spacing (organizer on the left, report number on the right).
- Axis labels: Inter 600 11px. Footer: column heads Inter 700 10px uppercase, 1.8px letter-spacing, cobalt; values Inter 600 13px ink; notes Inter 400 11px #6B6B6B.

Layout:
- 48px side margins. A 4px ink bar across the top at y 30, the header strip below it, then a 1px ink rule at y 64.
- Title block top left, the chart across the full width from about y 262 to y 482 (the lower half), overlapping the ghost numeral.
- Footer from y 520: a 2px ink rule, then four equal columns separated by 0.75px ink verticals, each with a head, a value line and a note (dates, venue, the headline comparison, credits with "Source: ..."). A 2px ink rule closes the page 12px above the bottom edge.

Axes and grid:
- Three dotted gridlines (0.6px ink, dash 1 3, 55% opacity) across the full width, with values like "50K" in Inter 600 11px #6B6B6B sitting 5px above each line at the left margin.
- A 1.5px ink baseline. x labels every five years in Inter 600 11px ink, 19px below the baseline, with 5px ink ticks; the first label left-aligned, the last right-aligned.

Marks:
- Line chart: draw it as a flat filled area, solid #1F3FBF down to the baseline with straight segments, no gradient and no transparency, plus a 2.5px #132A8A stroke along the top edge with round joins. Multiple series become stacked flat areas, the lower ones in #132A8A and the ghost color used only for the numeral.
- Bar chart: square-cornered flat cobalt bars, about 70% of the band, sitting on the ink baseline in front of the ghost numeral; the latest bar in #132A8A. Value labels in Anton above the bars, in cobalt.

Labels and annotation:
- The latest value in Anton 30px cobalt, right-aligned just above the last point.
- One event annotation: a 1px ink leader line with two lines of Inter 700 10px uppercase text, 1px letter-spacing, right-aligned to the leader.

Avoid: gradients, shadows, rounded corners, legends inside the plot, more than one accent color, and letting the ghost numeral tint or overlap the title text in a way that hurts reading.

When you're done, render the chart and check that the ghost numeral reads as a background shape rather than data, the cobalt area has a crisp top edge, the footer columns line up on their rules, and the title's claim is arithmetically true.
