Switch to XHTML5 markup

The site now has polygot markup and can handle both XHTML5 and HTML5
parsing rules. My staging site will be XHTML but my main site will be
HTML5, just in case of parse errors.

If other tools (e.g. LightHouse) end up supporting XHTML5, I'll consider
switching the content-type to XHTML.

+---
+I've been planning on writing a big "meta" post explaining how this site is built, but first I want to reach a few milestones, most of which are IndieWeb-related. Here's what I've already done:
+
+- Microformats
+- More semantic markup: Creative Commons and Schema.org vocabularies
+- Web sign-in (using an IndieAuth service)
+- multiple types of posts
+- Sending Webmentions
+- Displaying Webmentions
+- User-sendable Webmentions with a form
+- RSS feeds for posts and notes
+- Atom feed for posts and notes with ActivityStreams metadata
+- Automatic POSSE of bookmarks to TinyGem (bookmarking service)
+
+However, I still have a ways to go. Here's what I plan on adding:
+
+- Add some semantic markup to list online "friends", probably using [FOAF ontology](http://xmlns.com/foaf/spec/)
+- Preview Webmention entry contents
+- Related to previous point: create a blogroll
+- Automatic POSSE of notes to Fedi (it's mostly manual right now)
+- Combined Atom feed
+- WebSub
+- Permalinks for bookmarks
+- Atom feed for bookmarks
+- Automatic POSSE of bookmarks to Fedi
+- Time-period based pagination/navigation on notes/posts page.
+
+Once I finish the above, I'll be ready for a "meta" post. Some more tasks after that:
+
+- Run my own WebSub hub.
+- Add my own front-end for search results (my first non-static content).
+- Pingback support
+- Create a webring. What I've learned while doing the above will inform inclusion criteria.

+I'm in partial agreement with this take.
+
+On one hand, expectations change with time. Most people outside my bubble look at interfaces I like using and say they look "ugly" and that they're "weird" (their words); they wouldn't have said that when I was younger.
+
+On the other hand, some "annoyances" are actually removable *barriers*. Accessibility comes to mind. If you take software that does not work with assistive technologies (ATs) and fix it, AT-users might move on to the next accessibility issue. But they'll be markedly happier than before, when they just couldn't use it.
+
+Similar examples include localization and compatibility.
+
+Man, positive takes like this feel really out of character for me.

 I _highly_ encourage giving it a read; it's the perfect example of fuzzing with sanitizers to find a vulnerability, reproducing the vulnerability (by writing a tiny C program), _then_ diving into the source code to find and fix the cause, and finally reporting the issue (with a patch!). When source isn't available, the vendor would assume responsibility for the "find and fix" steps.

 By default, web browsers can share near-arbitrary identifying data with a server by executing near-arbitrary JavaScript, or store this information for future transmission. I have disabled this behavior with a `Content-Security-Policy` HTTP header that forbids script loading (`script-src: none`), script execution (`sandbox`), and making connections for any purpose other than downloading a page a user navigated to (`connect-src`).
 
-By default, web browsers may "pre-fetch" DNS queries for links on a page, potentially leaking information to third parties without a user's consent; I have disabled this behavior with the <code>X-DNS-Prefetch-<wbr>Control</code> header.

This header is respected by Chromium, Firefox, and Chromium derivatives (e.g. Google Chrome, Microsoft Edge).
 
 By default, user agents using HTTPS may contact a certificate authority to check the revocation status of an TLS certificate. I have disabled and replaced this behavior by including an "OCSP Must-Staple" directive in the TLS certificates used by my Web servers.
 
 By default, user agents using HTTP or HTTPS may share a "referring" location with the destination website when following a link. I have disabled this by sending a `Referrer-Policy: no-referrer` header.
 
-By default, Web browsers may share characteristics about the user's hardware, connection type, and personalizations using Client Hints and media queries. Browsers may request Web content according conditionally, in response to a `media` attribute in HTML or XHTML documents. Browsers may leverage stylesheets that use media queries to select varying `background-image` files. No Web content on seirdy.one will send network traffic in response to media queries except <code>prefers-color-<wbr>scheme</code>, assuming the use of a standards-compliant browser. Media queries and client hints will have no impact on HTTP responses except for dark image variants. This is a single binary piece of information that isn't enough to let me realistically identify anyone.
