Streaming-friendly profile (applied)

• In "1080p/4K", 1080p is ranked above 2160p and Upgrade Until = 1080p, so a 4K file grabbed as a fallback is replaced once a 1080p release appears.
• 2160p stays allowed only as a fallback.
• Blocked custom formats, each at −10000: TRaSH AV1, Not Original language (the release's audio isn't the film's original language), Sing-Along versions, and Foreign dub (dubbed-only releases).
• 2160p size caps in Quality Definitions: WEB about 150 MB/min (about 20 Mbps), Bluray about 200 MB/min (about 27 Mbps).

Optional

TRaSH's two-instance radarr-4k setup, with a 4K library that isn't shared.
