[User Story] Blog categories too restrictive; no RSS feed for subscribers

[coderabbitai]

Summary

1. Categories type hardcoded to only two values

src/lib/types.ts:

export type Categories = 'sveltekit' | 'svelte';

Any blog post with a different category (e.g., 'life', 'tech', 'anime') will cause a TypeScript error.

Fix: Broaden the type to accommodate real content:

export type Categories = 'sveltekit' | 'svelte' | 'tech' | 'life' | 'anime' | (string & {});

2. No RSS/Atom feed

There is no feed endpoint, making the blog undiscoverable to RSS readers.

Fix: After extracting getPosts() to src/lib/server/posts.ts (see Architecture issue), add src/routes/rss.xml/+server.ts:

import { getPosts } from '$lib/server/posts';
export async function GET() {
  const posts = await getPosts();
  const xml = `<?xml version="1.0" encoding="UTF-8"?>
<rss version="2.0"><channel>
  <title>lora-sys Blog</title>
  <link>https://your-domain.com/blog</link>
  ${posts.map(p => `<item>
    <title>${p.title}</title>
    <link>https://your-domain.com/blog/${p.slug}</link>
    <pubDate>${new Date(p.date).toUTCString()}</pubDate>
    <description>${p.description}</description>
  </item>`).join('')}
</channel></rss>`;
  return new Response(xml, { headers: { 'Content-Type': 'application/xml' } });
}
