* fix: improve Mermaid diagram implementation (#1213) This commit addresses multiple issues with Mermaid diagram rendering and adds significant improvements to the user experience. - Fix `<br/>` tags rendering as literal text instead of line breaks - Fix flash of raw mermaid code before diagram renders - Fix Gantt chart rendering issues in dark mode - Fix diagrams briefly showing during theme switch re-render - Fix expand modal showing diagram left-aligned before centering - Add fullscreen expand modal with pan/zoom functionality - Add toolbar with zoom controls (zoom in/out, reset, fit to screen) - Add keyboard support (Escape to close modal) - Add per-diagram transparent background via `%%transparent%%` directive - Add comprehensive configuration options: - `look`: classic or handDrawn (sketch style) - `lightTheme`/`darkTheme`: theme selection per mode - `lightThemeVariables`/`darkThemeVariables`: custom theme colors - `securityLevel`, `htmlLabels`, `maxTextSize`, `maxEdges` - `fontSize`, `fontFamily`, `curve`, `logLevel` - Switch from ESM to UMD bundle for faster initial load (~1s vs 2s+) - Lazy-load panzoom library only when expand modal is opened - Pre-render alternate theme during idle time for instant theme switching - Cache rendered diagrams to avoid re-rendering on theme toggle - Move all inline CSS to article.scss using SCSS nesting - Extract helper functions for better maintainability - Use data attributes and event delegation for cleaner handlers - Reduce mermaid.html from 411 to 177 lines (57% reduction) - Add comprehensive mermaid-diagrams example post with all diagram types - Document all configuration options in hugo.yaml * refactor: extract mermaid inline JS to TypeScript module Move ~155 lines of inline JavaScript from mermaid.html partial into assets/ts/mermaid.ts. The partial shrinks from 179 to 36 lines and now only contains modal HTML markup and Hugo Pipes build/import logic. - Deduplicate initWithTheme() and renderOffscreen() helpers - Enable minification via Hugo Pipes js.Build in production - Remove user-configurable mermaid version from params.toml --------- Co-authored-by: delize <4028612+delize@users.noreply.github.com>
