- Descriptions now render Markdown or sanitized HTML via [includes/db.php](/Users/tyemeclifford/Documents/GH/mediaplayer/includes/db.php).

Public player descriptions render formatted HTML on the homepage.
Catalogue cards, embed meta tags, and social metadata use safe 
plain-text excerpts.
Add/edit admin pages now use a rich description editor that preserves 
pasted HTML styling, with a textarea fallback for no-JS.
External/YouTube-imported descriptions are sanitized before storage.
README now documents Markdown/HTML description support.
