Scrapes the PAWS adoptable cats page and republishes the listing as an RSS 2.0 feed — one item per cat, with a plain-text summary and a rich HTML card (photo + details + link back to PAWS).

Each <item> includes:

• <title> — Name — Sex, Age (with (adoption pending) suffix when applicable). Example: Bahama — Female, 5 years 2 months.
• <link> — the cat's PAWS detail page (or the listing URL when none exists).
• <guid> — the detail URL (permalink) when available, otherwise a stable paws-cat:<name> token.
• <enclosure> — the cat's photo URL.
• <description> — a plain-text one-liner for list previews. Example: "Bahama is a 5 years 2 months old female Domestic Shorthair cat available for adoption at PAWS - Lynnwood."
• <content:encoded> — a self-contained HTML card with photo, a labeled details table, and a "View on PAWS →" link. Styles are inlined so most readers render it correctly.

Adoption-pending cats show a name and photo but PAWS hides their details, so the other fields come back null and the title is suffixed with (adoption pending).

The feed asks readers to poll as often as they're willing to:

• HTTP: Cache-Control: no-store, no-cache, must-revalidate, max-age=0 (plus Pragma/Expires for older clients).
• RSS: <ttl>1</ttl> and the sy: syndication module's updatePeriod=hourly / updateFrequency=1.
• lastBuildDate and pubDate are regenerated on every response so the feed always looks new.

A 5-minute server-side cache of the parsed cat list keeps us from hammering paws.org on every poll; it can be bypassed with ?fresh=1.

Rendering mermaid diagram...

• main.ts — HTTP routing, caching, query params, RSS XML generation.
• scraper.ts — fetch + cheerio parsing of the PAWS markup into Cat objects.
• test.ts — runs the scraper against the live site and prints a summary.

• PAWS serves server-rendered HTML, so a plain fetch + cheerio works well — no headless browser needed.
• The parser keys off PAWS's card-block__* CSS classes. If PAWS redesigns their site, update the selectors in scraper.ts.
• Photos are hosted on Petango (PAWS's adoption management system); promo cards are filtered out by requiring the image URL to be on petango.com.
