* fix: preload Google Fonts to reduce layout shift
Move font loading from footer JS to head with preconnect and preload
hints. This reduces CLS by ensuring fonts load earlier in the page
lifecycle instead of being dynamically inserted after footer loads.
* style: reorder custom font inclusion in head template

* 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

* Add support for Mermaid diagrams in markdown content
This commit introduces native Mermaid diagram rendering to the theme.
Following Hugo’s official documentation, a new custom code block renderer
(`render-codeblock-mermaid.html`) was added under `layouts/_default/` to
detect Mermaid code blocks and inject the necessary script flag into the
page context.
Additionally, the `baseof.html` template now conditionally includes the
Mermaid JS module from the CDN when a page contains a Mermaid diagram:
{{ if .Store.Get "hasMermaid" }}
<script type="module">
import mermaid from 'https://cdn.jsdelivr.net/npm/mermaid/dist/mermaid.esm.min.mjs';
mermaid.initialize({ startOnLoad: true, theme: 'neutral' });
</script>
{{ end }}
This enables rendering of fenced code blocks using the `mermaid` language
in markdown files without requiring any external preprocessing.
* Create article/components/mermaid and fix script version
