A fully self-contained music player component with playlist management, LRC lyrics syncing, progress bar, volume control, shuffle/repeat modes, and fade animations. It supports both local audio files and remote playlists via the Meting API. The component manages its own state (current track, playback position, loop mode) using Svelte stores and persists user preferences (volume, playlists) to localStorage. It integrates with the site's theme system for styling and includes a compact/mini player mode. This is a polished, reusable audio player that could be extracted into any Svelte or Astro project with minimal changes.

Implements a custom HTML element (<table-of-contents>) that automatically generates a table of contents from heading tags within a container. It uses IntersectionObserver to track visible headings and highlights the current section. It supports a floating panel mode (detachable button + sidebar panel) and integrates with Swup for SPA-like page transitions. The component is self-contained, emitting no global state, and can be easily embedded in any static site to provide interactive TOC navigation.

A custom rehype plugin that transforms inline music references into interactive, styled music card embeds in markdown content. It fetches album cover art and metadata from the Meting API, renders a player with audio controls and animated lyrics (LRC), and applies the site's theme variables for consistent styling. The plugin is configurable via inline attributes (service, id, type, auto) and handles both remote and local audio sources. This demonstrates a sophisticated blend of static site generation and client-side interactivity, making it a reusable pattern for any markdown-based site that wants rich music embeds.

An Astro component that preloads SVG icons from the Iconify API as inline SVGs to avoid runtime JavaScript overhead. It accepts a list of icon names and fetches them as a single request (via Iconify's batch endpoint), then renders them as hidden SVGs in the page head. Other components can reference these preloaded icons via their ID. This pattern eliminates the need for a heavy icon library at runtime and ensures icons are immediately visible without flash-of-missing-icon. It's a clean, reusable solution for optimizing icon delivery in static sites.
