shweetandClaude Opus 5.5 6f112ab231 HUD pass, weapon and trinket rework, and font arrows
HUD:
- Hotbars fit a quarter of the screen, dropping to small then tiny slots
  (thinner outlines when tiny), with cooldown bars matching their size.
- HUD elements are drawn on their own layer and composited at one
  opacity: hotbar slots are see-through until hovered, the rest fade
  while hovered.
- Rival windows fit the right column in at most two rows, shrinking
  icons then font, then dropping icons for name, health and ping bars.
- Tooltips number equipped items' slots and say Recoil for weapons that
  only push back. Previews use arrows, spread uses degrees.
- Crosshair fills in and shakes with charge, and weapons shake after
  firing until their cooldown ends. DPS and speed meters off by default.

Gameplay:
- Dual Wield stacks: each copy fires another recently held weapon from
  a fanned off-hand, at its own level's cut.
- Flamethrower: no slowing, smaller fireball with some recoil, and an
  airblast that knocks others away.
- Iron Weights slam on any landing faster than a plain fall (platforms
  too), stacking radius and damage, and speeding fast falls.
- Stuck arrows are one-way ledges until they fade, matching their
  (slightly larger) hit size. Attacks now collide with slopes.
- Halved Tesla Coil, Recoil Coil, Diazepam, Shock Absorber, Feather and
  screenshake values.

Art and tools:
- Weapon and trinket icons merged into one sheet each (normal, small,
  tiny), cells in catalog order. Grimoire wisps stand upright.
- Fonts gain the degree sign and four arrows, decoded from UTF-8.
- Menu fighter preview walks at quarter speed.
- Unequip from either catalog tab by right click or gamepad.

# Exports the game's fonts as atlases (resources/font/<name>.png) with a .fnt file each (JSON) that the game reads
# them by:
# tiny hand-drawn here, 3 pixels wide with a descender row, for squeezing text in
# small pixel_purl.ttf at its native 16 pixels per em, the game's usual text
# big small at twice the size, pixel for pixel, for text drawn twice as big
# huge small at three times the size, for text drawn three times as big
# Each glyph sits in its own cell, 16 to a row, drawn where the game puts it relative to the line's top-left, so the
# PNGs can be redrawn by hand afterwards (keeping to the cells, or changing the .fnt to match).
#
# A .fnt file holds the image, the scale it's drawn for (which size of text the game picks it for; tiny has none,
# being picked by name), the line height, the outline's thickness, and per character its cell in the image (x, y, w,
# h), where the cell goes relative to the pen at the line's top (dx, dy), and how far the pen then moves (advance).
#
# Existing files are left alone, so hand edits survive; --force writes them all again.
