One hidden <svg> of <symbol>s, for a host that shows many glyphs and
wants each path in the document once. Inject it once, then place glyphs with
iconUse. Symbols carry the path and viewBox only; stroke and fill inherit
from the <svg> around each <use>, so one sprite serves every weight.
Default: every tool glyph. Repeated ids collapse to one symbol, since a
duplicate element id is an invalid document.
