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.
Some old browser engines don't fully support hyphenation, so they need
some extra help. Now, the entire site should fit in a 150 CSS-pixel wide
viewport.
Clean up some link text too so the text alone is more useful.
All pages except bookmarks can now fit on your smartwatch without any
adjustments, so we can disable the auto-zoom-out-to-match-mobile
wizardry that watch browsers do (comparable to the
zoom-out-to-match-desktop stuff that early mobile browsers did).
Yay.
