# Publication-Grade Figure Rules _A checklist for correct, legible, internally-consistent scientific figures. This skill does not impose a visual house style — frame, font, and palette are parameters. Once loaded, call `apply_figure_style()` before plotting._ ## §0 Scope **Load trigger.** This skill is for **final-deliverable figures** — those shipping in a report, paper, or export, or saved as a file that will be kept — not for exploratory/intermediate plots (quick looks, EDA, sanity checks), which are drawn plainly without it. Once loaded, "every plot" below means every plot you render toward the deliverable. §1–§3, §8, and §9 are **correctness** — they apply to every plot, in every context, and have no aesthetic content. §4–§7 are **guidance** — defaults that produce a clean result but that a deliberate alternative can override (individual rules inside §4–§7 that state a factual/perceptual invariant — e.g. §4.4 semantic-zero centring, §4.5 CVD, §6.9 leader anchoring — still bind). This skill is the inner tier (make one plot good); `figure-composer` assembles these panels into one multi-panel figure and `paper-narrative` reviews a whole paper's figure arc — the outer two tiers of the stack. --- ## §1 Data fidelity & self-consistency **1.1 Excluded rows.** A row marked excluded or flagged in the source data is either omitted entirely or drawn with a visually distinct open/hatched marker and named in the key. It **never** enters a summary statistic plotted alongside th
