The top-bar theme switch looked heavier and larger than the icons beside it.
An earlier commit dropped the `far` modifier from fa-toggle-theme, which moved
the glyphs to the Solid face. The reference's glyphs are the outline variants
(FA4's sun-o / moon-o), and in FA5 those live in the Regular face — so the
Solid replacement reads bolder and visually bigger at the same 1em size, while
the neighbouring account icons stay on the lighter Regular-style SVG set.
Restore `fa far fa-toggle-theme` on all three placements: desktop navbar,
mobile header, and the floating rail. The .fa-toggle-theme::before/::after
composite rules only handle positioning and the slide transition, so they are
unaffected by the face swap.
legacy-navigation-contract already asserts `fa far fa-toggle-theme` and passes
again; full suite 999/1000 with the pre-existing frontend-lifecycle failure.
