  "$description": "Slide-deck-only spacing scale for sales collateral decks (pilot kickoff, customer 101, internal team, partner enablement). 16:9 master, 1280x720px = 13.33in x 7.5in (standard widescreen). Every gap has a floor AND a ceiling per the project rule that AI agents optimize toward maximums without bounds. Mirrors tokens/spacing/print.json conventions. UNIT CHOICE NOTE: master width/height are CSS pixels (1px = 1/96in for print), NOT points (1pt = 1/72in). The equivalent-physical-size pt notation would be 960pt x 540pt; px was chosen because it matches the universal slide-shorthand used by PowerPoint, Keynote, Google Slides, and web design tools (where '1280x720 widescreen' is recognized at-a-glance). Both produce the same physical size in PDF rendering. Internal type sizes (frame, type, footer) use pt (typographic conventional); only the master uses px. Reviewed by gemini-code-assist on PR #43 2026-05-03 — Gemini suggested pt (960x540), Verdigris kept px for consumer recognition; both mathematically equivalent.",
