1.5.3: shared-menu 1.2.2, and run the glyph style instead of reading it

678f1f03 is withdrawn. It hard-coded the icon box at 36x34, and WordPress
declares that parent three times with different sizes — 36x34 open, 35x30
folded, 34x30 under 960px — so a fixed number is correct in one state and 4px
too tall in the two a laptop is usually in. cache-manager measured where the
ink lands rather than where the box is and found it worse than that: the glyph
moved from 2.5px above centre to 2.5px below in the folded states, the same
error mirrored, in a state that had been nearly right. 1.2.2 removes the number
entirely with width/height at 100%.

1.5.2 is already published with 678f1f03, so this tree shipped the withdrawn
version. Checked before anything else, because a later candidate fatalled on
every admin page with "Unknown format specifier": that file was never taken
here, and the published 1.5.2 emits its stylesheet cleanly — verified by
running sprintf over its format string rather than reading it. So the shop is
cosmetically off in folded menus, not broken.

New assertion, and it is the one this round is really about: the style
function is INVOKED and its output captured, rather than the source being
read. The fatal that prompted it survived three sessions reading the file,
a clean php -l, a clean PHPCS, and two browsers agreeing about the CSS —
because every one of those was fed the stylesheet by hand rather than through
the printf that produces it. A literal per-cent must be doubled in a format
string, and nothing that looks at the file can see that.

Proven red with that exact fault rather than an arbitrary one: undoubling the
per-cent gives "ValueError: Unknown format specifier ';'".
