Theme's title was coming out at the normal weight — <summary> does not
inherit an <h1>'s boldness, so sitting it under .admin-h1 got the size,
colour and spacing but not the type. It now matches the other section
headings exactly.
The caret moved to the right of the words. A marker in front pushes the
heading out of line with every other one on the page; behind it, the section
still reads as "Theme" first and the caret only says there is more.
Written as the pattern rather than as Theme's own styling: any section that
folds is a <details class="admin-fold"> headed by a
<summary class="admin-h1 admin-fold-title">, and the whole row is the target.
