v0.1.0

Initial release.

• image-compare block: before/after images, caption, configurable start position (0–100 %)
• Responsive <picture> output (WebP + JPEG) via Kirby's built-in srcset() — no external image pipeline
• Dependency-free vanilla JS slider (~50 lines): mouse, touch, and keyboard (arrow keys)
• Themeable through CSS custom properties
• Panel preview showing both images side by side
• Zero config: frontend CSS/JS are injected automatically, once per page
