# Paper Poster (HTML): measurement-gated poster generation One HTML file styled for an exact print canvas (`@page { size: W H }`), rendered to PDF via Playwright print emulation. **Iterate by measuring, not eyeballing** — the screen preview lies; only print emulation at the correct viewport tells the truth. Core gate machinery is adapted from [posterly](https://github.com/Chenruishuo/posterly) (MIT, © 2026 Ruishuo Chen — see `NOTICE.md` and `LICENSES/posterly-MIT.txt`); ARIS adds style discipline gates, figure-provenance gates, the cross-model review loop, and the anti-patch-loop fix vocabulary. ## Why this skill exists (the failure it prevents) A predecessor pipeline produced a poster with **30+ colors, zero real paper figures, a screen-pixel canvas, and tiny formulas floating in oversized boxes**, then spent 12+ review rounds making it *worse* — each round added a new badge color or bespoke SVG patch. The cure is structural, not exhortative: 1. **Hard gates run before any aesthetic opinion** (alignment, style, assets must PASS first — a reviewer never sees an unmeasured poster). 2. **A closed fix vocabulary** — visual-review fixes can only touch design tokens, whole catalogued components, content rebalance, assets, or canvas choice. New inline styles / new hex values / bespoke decorations are structurally forbidden. 3. **Two-hue discipline as a machine check**, not a style suggestion. 4. **Real paper figures with provenance manifest**, or the gate fails. ## Me...
