pele_dart 1.13.0+1

Pure-Dart Mermaid diagram layout and SVG renderer ported 1:1 from obsidianmd/pele, outputting themeable CSS-variable SVG and flattened vector_graphics SVG.

1.13.0+1

• Refine README.md typography, visual showcase layout, and Pele brand mark for pub.dev and GitHub rendering.

1.13.0

• Initial public release of pele_dart, version-locked 1:1 to upstream obsidianmd/pele (v1.13.0, commit 3a2f075ee0c3d914f0fad3545fc0f193693975ac) created by Steph Ango (kepano) and the Obsidian team.
• 33 Supported Diagram Families:
  • Core Mermaid diagrams (flowchart, sequence, class, state, er, gantt, gitGraph, mindmap, pie, info).
  • Extended & architecture diagrams (agentflow, architecture, block, c4, cynefin, eventmodeling, ishikawa, journey, kanban, packet, quadrantChart, radar, railroad, requirement, sankey, swimlane, timeline, treemap, treeView, usecase, venn, wardley, xychart).
• 100% Byte-for-Byte Upstream Parity: Verified against upstream obsidianmd/pele v1.13.0 across 787 canonical, gallery, and test corpus diagrams (33/33 canonical + 232/232 gallery + 522/522 upstream corpus).
• Dual SVG Output Modes (SvgOutputMode):
  • SvgOutputMode.flattened (default): Resolves --pele-* and --_* CSS custom properties, color-mix(in srgb, ...), calc(...), currentColor, baseline-shift, and inline style attributes against PelePalette (PelePalette.light, PelePalette.dark, or custom palettes) for static SVG 1.1 renderers and Flutter's vector_graphics_compiler.
  • SvgOutputMode.cssVariables: Emits upstream obsidianmd/pele's exact theme-reactive CSS custom property SVG.
• Core API: render(), renderMermaid(), parse(), detectType(), supports(), flattenPeleSvg(), register(), registered(), RenderOptions, ParseOptions, PelePalette, PeleError, TextMeasurer, IconResolver, and MathResolver.
• macOS 3-Way Comparison Studio (studio/): Desktop workbench for side-by-side visual rendering, visual pixel/curtain diffing, and SVG text diffing across pele_dart, obsidianmd/pele (JS), and mermaid.js, with a live CSS style editor and dynamic .mmd/.mermaid folder browser (studio/diagrams/).
