Tips navigate the page reading local fill level — how dark or light a cell is relative to the current phase. Dark phase: heavy contour at the frontier, fine hatching inside; new tips spawn where the page is emptiest. Light phase: the same rule inverted — white ink carves back through the black. When the page nears black the breath turns; when it nears white the breath turns again. One teacher: the page itself.

// fill level = how "filled" this cell is in the current phase: // dark phase → fill = brightness (0=empty space, 1=black) // light phase → fill = 1−brightness (0=already white, 1=black to erase) fill < 0.05 heavy contour 2.2px · 0.92 // the frontier — first mark / first erasure fill < 0.20 secondary 1.5px · 0.78 // just inside fill < 0.45 fill 0.85px · 0.58 // the body fill ≥ 0.45 interior hatch 0.52px · 0.20 // fine marks — accumulate slowly to solid // moods: TENDRIL · CURL · SPIKE · HATCH · SCRIBBLE (unchanged from v3) // // spawn: new tips plant at the most-empty zone (dark) or most-black zone (light) // → the mass expands outward rather than concentrating at center // // spike: only fires at the frontier — where fill < 0.08 and neighbours > 0.15 // → teeth appear at the silhouette edge, not scattered through the interior // // phase switch: // avg brightness > 0.82 → light phase (white ink erases the black) // avg brightness < 0.18 → dark phase (black ink builds again)
