polish: pure-black bg + search bar fix + variant E nav glow + My Media hide

Grey #101010 stripe at bottom of pages: jellyfin-web theme.css:44-50
sets .backgroundContainer + html to #101010, neither Cineplex nor
prior overlay overrode it. Added rule forcing #000 across html, body,
.backgroundContainer, .skinBody, .mainAnimatedPages, .pageContainer,
#reactRoot under body.arrflix-themed.

Search input: stock cyan focus ring (#00a4dc, theme.css:262-272)
swapped for borderless slab + 2px red bottom on focus + soft red
box-shadow halo. Cineplex/Netflix-faithful.

Movies/Series nav: variant E "cinematic glow" picked from preview.
Active state = red text + text-shadow halo + font-weight 700. JS
hash matcher toggles .arrflix-nav.active when location.hash matches
#/movies.html or #/tv.html (and short forms). hashchange listener +
existing setInterval keep state in sync.

My Media row: .homePage .homeSectionsContainer .verticalSection.section0
hidden — matches prod which had it hidden via different mechanism.

Snapshot at snapshots/2026-05-09-v6-stable/index.html bumped to
md5 2c8f5d5f7c99611fa93d15c34fbe35d1; same as prod and dev.
