Chart Prompts

Restyle my chart in the "Celadon" 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: looking down into a pale jade-glazed bowl. Soft, cool and calm, with a fine crackle in the glaze and one warm iron-brown reference line.

Colors (use these exact values):
- Canvas: #D6E3D2 (celadon glaze), darkened toward the corners by a radial overlay of #9FB79A from 0% opacity at 60% radius to 35% at the edge.
- Bowl interior: an ellipse centered at (480, 332), 470 x 263 px radii, filled with a radial gradient: #E8F0E4 at full opacity in the center, 75% at 72%, fading to transparent at 90%, a thin rim of #B7CBB2 at 55% opacity at 97%, then transparent.
- Deep jade #2F5E4E for the data line, markers and gridlines (at 16% opacity). Iron brown #8A6B4A for the target line and the kiln note. Text: #1F3A31 for the title, #5B7268 for secondary text.

Typography (Google Fonts):
- Nanum Myeongjo 800 for the title (32px, #1F3A31) and end value label (20px, jade); 700 for annotations (13 to 15px).
- Nanum Gothic for the subtitle (15px, #5B7268), tick labels (12px) and notes (12px); the final year label 700 in #1F3A31.

Layout:
- Title at x 64, y 70, stating the finding. Directly under it an incised underline spanning the title's width: a 1.6px jade line at 70% opacity at y 88, with a 1px #F3F8F1 line at 90% opacity 1.8px below it, like a cut with a pale lip.
- Subtitle at y 116 with measure, unit, maker and period.
- Plot from x 150 to 842, y 202 to 462, sitting inside the bowl ellipse.
- Footer at y 572: source at left; at right, a kiln firing note in 12px iron brown preceded by a small 3px-radius iron-brown ring (for example "Reduction firing, 1,280 °C, 14 hours").

Texture:
- Crackle: build a jittered lattice of points about 46px apart (each moved up to 40% of the spacing), join neighbours right and down (90% of the time) and occasionally diagonally (22%), each join kinked once at a jittered midpoint. Stroke 0.8px #1F3A31 at 10% opacity, drawn over the bowl as well. Add about 160 short 8 to 26px crazes at 0.5px, 7% opacity.

Axes and grid:
- Faint horizontal gridlines only; y labels as percentages right-aligned 14px left of the plot. A 1px jade baseline at 45% opacity with 6px ticks at major years and 3px ticks otherwise; label every third year.

Marks:
- Line chart: a 2px jade line (monotone smooth curve) with round markers of radius 4 filled jade with a 1.8px #E8F0E4 ring, the latest point radius 6 with its value in Nanum Myeongjo 800 20px to its right. A faint jade area fill at 7% opacity. The target is a 1.6px iron-brown line dashed 7 on, 5 off, labelled "Target 80%" in Nanum Myeongjo 700 14px iron brown just above its left end.
- Bar chart: jade bars with 3px rounded top corners and a 1.8px #E8F0E4 inner keyline at the top, about 55% of the band wide, the dashed iron-brown target drawn across them; value labels in Nanum Myeongjo above each bar.

Labels and annotation:
- Annotate one notable dip with a short iron-brown leader and a two-part kiln note: a Nanum Myeongjo 700 13px iron-brown headline and one or two 12px Nanum Gothic lines in #5B7268.

Avoid: saturated greens, hard black, heavy borders, drop shadows and letting the crackle get darker than 10% opacity.

When you're done, render the chart and check that the title's claim about the target is true for the data, the crackle stays a whisper behind the line, and the oval vignette frames the plot without clipping any labels.
