Font Awesome shipped 137 kB of css and eight webfont files for seven glyphs: the external-link arrow, the search magnifier, the glossary link icon and four social icons in the footer. Those are inline svgs now (path data from Font Awesome Free 6.2.1, CC BY 4.0, attributed in ui/NOTICE), sized and colored via a small .svg-icon utility class. site.css shrinks from 146 kB to 48 kB and the webfonts/ directory disappears from the bundle. The fa-* checklist selectors in doc.css stay: they come from upstream and draw the check marks with css content, independent of any icon font. Also removes the inlineDynamicImports rollup option (vite 8 warns it is redundant for non-code-split builds).

Description
Second slice of the performance batch, stacked on #889 (retargets to main when that merges).
Font Awesome shipped 137 kB of css + eight webfont files (~350 kB) for exactly seven glyphs: the external-link arrow ({external-link-icon} in the playbooks + 4 uses in the universal navbar), the search magnifier, the glossary link icon, and the xing/linkedin/github/twitter icons in the footer.
.svg-iconutility class for fill/alignment, sizes matching the previous fa-xs/fa-sm/default rendering.site.css: 146 kB → 48 kB.webfonts/disappears from the bundle.fa-*checklist selectors in doc.css stay - upstream draws those check marks with csscontent, no icon font involved.inlineDynamicImportsrollup option that Vite 8 warns is redundant.Review hint
Since this is stacked, there's no automatic deploy preview. The icons to eyeball once #889 merges (or via a temporary draft PR against main): external-link arrows in the top navbar and content links, the search icon in the header, footer social icons, and the glossary's link icons.
