Inter, one file where WordPress listed two, and a pin heading on line

Inter (#11): the pages are set in Inter's variable font, served from the
binary at /inter.woff2 as the icon is, with its OFL licence beside it in
web/. Classic keeps Lucida Grande, the 2004 app's face.

Double audio (#12): WordPress numbers each audio player on a page by
adding ?_=N to its file's URL, so a post that embeds the file it encloses
listed it twice, and it was downloaded twice. The parser keeps the first
of an item's enclosures that differ only by that number. At startup the
repeats already stored fold into the first; where only the repeat had
been downloaded its file moves to the first rather than being deleted.

Pin heading (#13): the rows' icon buttons kept the browser's side
padding, which pushed their 16px icon 3px right of centre, and the
heading's icon sat at the left of its column. Both are centred now, and
the heading row takes the pixel of border the rows have, so every
heading sits over its column.

Closes #11, closes #12, closes #13.
