One block per month. Rows = habits, columns = days. Each habit keeps its own motif, and ink density = % of goal. A perfect day turns its whole column yellow, so streaks appear as vertical yellow bands. Habits added or dropped mid-year show as rows appearing or vanishing.
Rows = weeks, 7 big cells per row. Each day splits into one sub-cell per active habit, so the subdivision changes when your habit list changes (5 → 7 → 6 → 9 here), like the varied cells in the artwork.
One small tile per day, read like a page. The tile's motif comes from the day's strongest habit, and its density comes from the day's overall score. Perfect day = yellow, rest day = solid black. A 7+ day strong run (≥70% every day) gets a big circle; 21+ gets a bigger one.
0% = blank (no ink). 93% = 93% ink. A habit at ≥100% gets full density. Rest days are solid black.
