Five Font Awesome 4 icon names render nothing (FA4 names on a FA5 dependency)

[codeGlaze]

Five icon names in source are Font Awesome 4 spellings. The project depends on
org.webjars/font-awesome 5.13.1, where those names do not exist, so the elements render
nothing — on every browser, with the font loading correctly.

location	in source	should be
src/cljs/orcpub/dnd/e5/views/import_log.cljs:63	fa-pencil	fa-pencil-alt
src/cljs/orcpub/dnd/e5/views/import_log.cljs:192	:icon "fa-pencil"	fa-pencil-alt
src/cljs/orcpub/dnd/e5/views/import_log.cljs:39	fa-exchange	fa-exchange-alt
src/cljs/orcpub/dnd/e5/views/conflict_resolution.cljs:17	fa-circle-o / fa-dot-circle-o	far fa-circle / far fa-dot-circle
src/clj/orcpub/styles/core.clj:1127	.fa-caret-square-o-down	dead selector, matches nothing

The replacements are not guesses: they come from metadata/shims.json inside the webjar the
project already depends on. FA5 replaced the -o suffix with style prefixes (far is the old
"outline") and renamed 463 icons.

The sharpest case is conflict_resolution.cljs:17, the radio indicator in the homebrew import
conflict modal. .radio-icon has width:16px, so it reserves the space and draws nothing;
selection stays legible from the border colour, which is probably why nobody has reported it.

Five is the complete set — all 44 fa-* names in source were checked against the webjar's
1,605 SVGs. The webjar also ships css/v4-shims.css, which would fix all five in one
include-css, but renaming five is cheaper than carrying a 463-entry shim.

One trap for whoever fixes it: fa-pencil\b matches inside fa-pencil-alt, so a naive grep
also reports views.cljs:8520 as broken. That one is already correct.
