Omarchy Breakout v0.2.6

Replaces v0.2.5's literal wordmarks with handcrafted symbolic pixel art across the full campaign.\n\nEach board now has its own visual idea: terminal prompt, Arch mark, Tokyo torii and moon, desk, runner, hill, radio tower, campfire, envelope, book, rails, live wire, turbocharger, spark, cargo ship, cable, coin, rework cycle, rising shapes, crossed-out calendar, team, factory, official Omarchy icon, and one person inside a framework.\n\nThe complete 24-board contact sheet was visually reviewed at game scale, and regression coverage now rejects wordmark layouts.
