2.2.0

2.2.0

Mermaid diagrams now use OnePage's paper palette (Obsidian 1.15 / Pele), plus 13 new diagram color settings.

Obsidian 1.15 renders Mermaid with Pele. Pele ignores Mermaid themes and only reads CSS variables, so OnePage now owns --mermaid-* and gives diagrams the same language as the paper:

• Nodes: paper fill (one step of the secondary surface), 26% warm-ink border, 6px radius; subgraphs become the same rounded card as the Properties panel (opaque, 13px title)
• Edges: 55% text color; ==> main paths, sequence critical frames and notes use the accent color
• Semantic tags: :::key / risk / warn / ok / ext / muted map to the accent and callout inks; ext gets a dashed border, muted a fainter one
• Series colors (pie / XY / git / timeline / treemap): derived from the typographic heading colors and callout inks; in light mode each is mixed with 35% paper so large fills don't feel heavy (dark mode keeps the already-light values)

New Style Settings (Colors → Mermaid Diagram Colors)

• "Custom Diagram Colors" toggle: off by default, so diagrams keep following the paper / headings / callouts; turn it on to pin the fixed palette below
• 13 color options, one per mode: node fill / subgraph fill / border / text / edges + eight series colors
• The accent and ::: tags keep following the Accent / Callout settings; the toggle does not lock them

Compatibility

• Minimum Obsidian version stays 1.14.0; diagram styling needs Obsidian 1.15+ (older Mermaid never reads these variables and simply keeps its previous look)
• Verified with build / verify; diff:style reports zero differences in light / dark / demo / translucent; rendered flowchart, sequence, pie, gantt, cynefin, eventmodeling and treemap with the Pele 1.8 bundled in Obsidian 1.15.0
