0.2.0

Fixed

• PNG export no longer collapses inter-word spaces (switched the rasterizer from
  html2canvas to modern-screenshot).
• PDF export now prints the theme background (print-color-adjust: exact in PRINT_CSS) —
  dark themes no longer print on white.

Added

• Mobile support (isDesktopOnly: false) — the plugin now runs on iOS/iPadOS. All
  desktop-only APIs are platform-guarded. On mobile, PDF export writes a self-contained HTML
  file into the export folder and opens it via the OS (openWithDefaultApp); the user then
  prints or shares to PDF from there.
• Live theme switcher — the preview toolbar now has a theme dropdown for ephemeral try-on, a
  source label (from frontmatter / from default / ● unsaved) that disambiguates where the
  active theme comes from, and a Set button that writes theme: into the note's frontmatter
  via setNoteTheme (processFrontMatter). Fixes the „theme dropdown does nothing" confusion.
• User themes — drop .css files into the configurable themes folder (default
  Slide-Deck-Themes/); the frontmatter theme: value is the filename without the .css
  extension. Each file is a --sd-* token block with optional extra CSS; user themes inherit
  the built-in default theme's code-highlight and Mermaid styles. The Settings tab shows all
  valid theme keys live.
• Theme import/export — an Open in Finder button reveals the themes folder (drop files
  in); Export theme as .css writes any theme as an editable .css starting point; a toggle
  hides the themes folder in Obsidian's file explorer.
