--bg-elev-3 was referenced (spinner ring, search-clear hover) but never
defined in either theme, so var(--bg-elev-3) with no fallback produced an
invalid declaration — that's why the busy spinner ring was invisible
until it was switched to --border. Define it as a real elevation step
above --bg-elev-2 in dark (#34343f) and light (#e3e3dd).
Also define --accent-fg (#fff) explicitly instead of relying on the
inline var(--accent-fg, #fff) fallback.
Audited used-vs-defined custom properties: the only remaining "undefined"
one is --strength, which is set at runtime by JS on the password-strength
bar (has a 0% fallback) — intentional, not a bug.
