`resolution_pref` only gated eligibility, so every release was scored
against its own resolution's size band and a 23 GB 4K lost to an
at-target 1080p. Each step up the list is now worth `resolution_step`
points, seeded at 300: five gibibytes of 4K overshoot, so a 4K up to
27 GB wins and a bloated one still does not.
