0.1.0

First release.

Added

• Markdown notes → slides — a --- separator line splits a note into individual slides;
  YAML frontmatter (theme:, aspect:, minFontPx:) controls deck-level directives.
• Live preview pane (Open presentation preview command) — renders the current note as a
  slide deck in the right sidebar, scaled to the pane width, with a source-jump link to each
  slide's originating line.
• Theme isolation — slides render inside a sandboxed iframe, so the active Obsidian theme
  can never leak into the preview or the exports; a deck looks identical regardless of the vault
  theme.
• Four built-in themes — default (light), dark, serif, and high-contrast, selected
  per deck via the theme: frontmatter; each carries a matching code-highlight and Mermaid theme.
• Per-slide layouts — title, two-column, image-focus, section, and quote, chosen
  per slide with an HTML comment directive (<!-- layout: two-column -->) and a <!-- column -->
  region separator.
• Custom CSS — an optional CSS snippet (Settings) is appended to the deck styles for branding
  and tweaks, in both the preview and the exports.
• Fit-or-warn readability — each slide auto-scales its content down to a configurable
  legibility floor (minFontPx, default 24 px); slides that would need even smaller text are
  flagged as overflowing (with a click-to-source warning) rather than becoming unreadable.
• PDF export (Export presentation to PDF command) — prints the deck (one slide per page,
  exact geometry) via the system print dialog (choose "Save as PDF"), theme-isolated.
• PNG image-series export (Export presentation to image series command) — captures each
  slide via html2canvas and writes numbered PNGs into a configurable export folder.
• KaTeX math — inline $…$ and display $$…$$ math.
• Code highlighting — fenced code blocks highlighted by highlight.js (per-theme stylesheet).
• Accessible callouts — > [!note], [!warning], [!danger], [!tip], [!info] blocks
  rendered with redundant coding: border colour + geometric shape + visible label word (not
  colour-only; WCAG 1.4.1).
• Mermaid diagrams — fenced ```mermaid ``` blocks rendered as SVG (per-theme).
• EN/DE interface — all UI strings follow Obsidian's language setting (English canonical,
  German supported); the settings tab and every notice are localized.
• Settings tab — default theme, minimum body font size, image-export scale, custom CSS, and
  export folder.
• Pure-core architecture — src/core/** is Obsidian-free and Node-testable; a core-purity
  check and a realm-safety check run as part of npm test, alongside a real-bundle smoke test
  and 63 unit tests.

Notes

• Desktop only (isDesktopOnly) — PDF/PNG export needs a full browser DOM.
