- Reveal the prologue spawn box in recalculate_vision: the player owns no units
during the turn -1/0/1 cold-open, so unit-derived fog left the whole map black
and the wanderers invisible. Reveal the local player's box (LOS from centroid +
each wanderer hex) whenever a prologue is active.
- Prologue overlay: draw the real dwarf_wanderer / dwarf_tribe sprites, centered
on the hex (+ hex_center, was drawing at the corner), scaled to match in-game
units. Marker glyph kept only as a missing-asset fallback.
- Scale all unit sprites to 0.6 of hex width and city sprites to 0.75 via
DrawHelpers.scaled_sprite_size — Civ-like tile dominance instead of the tiny
native 64px blit that read as unreadable tokens.
- Add toggleable leveled Log autoload (dev/info/warn/error via MC_LOG_LEVEL,
default info); route prologue diagnostics through it with durable tags
(prologue / prologue-overlay), not objective ids.
