  "message": "Add dark mode theme support for Mermaid diagrams\n\nGitiles renders Mermaid diagrams server-side into SVG. Previously, all\nSVG shapes (nodes, subgraphs, edges, markers, text, and labels) used\nhardcoded light-mode hex values, causing them to display as glaring\nwhite rectangles with poor contrast in dark mode.\n\nThis change:\n- Defines CSS variables for Mermaid diagram elements (--mermaid-node-bg,\n  --mermaid-node-stroke, --mermaid-node-text, --mermaid-edge,\n  --mermaid-subgraph-bg, etc.) in doc.css under :root, light mode,\n  dark media query, and html[data-theme\u003d\"dark\"].\n- Adds semantic CSS classes (.mermaid-node, .mermaid-subgraph,\n  .mermaid-edge, .mermaid-arrow, .mermaid-shadow, etc.) to rendered SVG\n  elements in SimpleMermaidRenderer while preserving presentation\n  attribute fallbacks.\n- Selectively applies fill/stroke classes when custom style directives\n  are absent, preserving user-defined colors without stylesheet overrides.\n- Supports `color:` in `style` directives and computes background\n  luminance for custom-filled nodes (e.g. pastel database cylinders)\n  to preserve dark, readable text without stylesheet theme inversion.\n- Adds comprehensive unit tests in SimpleMermaidRendererTest covering\n  theme classes, custom styles, and text contrast on custom-filled shapes.\n\nChange-Id: Iac234a2dd627a06ecceb41c4fabbbbdd92233605\n",
