DommUI

Fixes
- The "attempt to call a nil value" error that repeated hundreds of times per
  battleground (and at login) is gone: the widgets below the minimap no longer
  hook Blizzard's layout.
- The loot window (LootFrame) is skinned again; it failed and stayed stock.
- Bags: the item level no longer errors on opening (the client removed two
  functions it used).
- Character: an enchant, a gem or any spell waiting for an item is cast on the
  slot you point at, without the blocked action the game reported.
- Raid and unit frames: rebuilding a large raid no longer runs past the
  client's script budget (every call that frame failed); deferred work is
  spread over frames.
- Unit frames carry no rounding: bars, portrait and selection ring are square,
  as the rest of the design is.
- Traveler's Log: no error when there is no vendor item.

Battleground map
- Flag maps: a carrier is named in one of seven zones (our base, our graveyard,
  our ramp, mid, their ramp, their graveyard, their base).
- Hovering a carrier puts its call on its flag (attack an enemy, defend ours),
  and a click sends it to instance chat.
- Which side each base's graveyard is on is set per map.

Panels: PvE
- The season's Mythic+ ranks drawn as the PvP ones: the highest reached, an
  arrow and the next, each in its rank's colour, with what each rank pays.
- Raid Finder and Dungeon Finder show up to two samples of what they may drop,
  with tooltip and Ctrl+click preview.
- Every Suggested Content card says what it pays.
- Timewalking: new banners per expansion; the weekly quest is found even when
  its title does not name the event, and shows what it pays.
- Traveler's Log wears the month's seasonal art, after a /reload too.

Skins
- Adventure Guide: cleaner boss buttons and loot rows; the creature buttons,
  the model and the side tabs keep their own art.
- A queue's ready check: each player's mark shows over their role.

Arena
- Before the gates open, opponents are drawn nearly whole (0.9); one out of
  sight during the match at 0.6.
