Hold the hover tooltip to the screen against the real font

The pixel-measured wrap passed the headless suite (which stubs text_width) but
failed three assertions under the real engine in the smoke harness:

- "Looking for:"/"Offers:" hints and the two-tone combo rows render at scale
  0.3 but the width budget -- and every other row -- is measured at 0.32, so a
  row that fit at 0.3 slipped over the budget once measured at 0.32 and clipped.
  Render those rows small as before, but bound their wrap at the 0.32 reference:
  a 0.3 row is narrower still, so it can only wrap early, never clip.
- wrap_measured word-split multi-word joker names, so a fusion's result read as
  "Fusion ready: Diamond" / "Bard ($12)" -- two jokers, not one. atomic() fuses
  a name or multi-word label into one unbreakable wrap token (spaces -> a \1
  sentinel, restored for measurement and output); applied to every joker name
  and tag label that flows through a wrapped row.

Smoke: 20/20 against the real Card:generate_UIBox_ability_table pipeline and the
real Fusion Jokers recipe table. Headless: 947 pass.
