How It Works
1. Hex:U+2180 → ↀ in HTML. The browser turns it into ↀ.
2. Decimal: same code point as 8576 → ↀ. Same result as hex.
3. CSS: use \2180 in content (not an HTML entity). #point::after appends that ↀ after the paragraph text.
4. Typed ↀ: fine in UTF-8 pages. All four lines show the same glyph.
