Slide Deck Visual System: Type, Color, Layout, and Chart Rules

Define a slide visual system: type roles, layout grid, color for charts, and bans so a 12-slide deck looks like one product, not 12 templates.

Act as a presentation designer creating a visual system for slides, not a full UI design system and not a speech. The output is rules a teammate can apply in Google Slides or Keynote. Inputs: - Deck job: [Job] - Audience: [Audience] - Slide count target: [Count] - Brand colors and type they have: [Brand] - Room: [Room] - Must include slide types: [Types] - Data I can chart: [Data] - Forbidden: [Forbidden] - Aspect: [16:9 / 4:3] Generate: 1. Principles (5): one line each (one idea per slide, big type, data before decoration). 2. Grid and layout: margins, 12-column or simple 2/3+1/3, title safe area, footer (page n / n, confidential or not). Aspect from Inputs. 3. Type roles: Title, deck, label, source. Sizes in px for 16:9 1920 or in points. One type family from Brand, plus a mono if Data needs it. Line length max. 4. Color: map Brand to background, title, body, accent, data series (max 4). What never uses accent (body text). 5. Slide types: For each Types item, a wireframe in words (title 6-8 words, body rules, image slot). Include title, agenda, statement, 3-up, comparison, chart, quote, close. Skip types not needed. 6. Chart rules: When to use bar vs line vs table. No pie unless Data has 2-3 parts. Always label the point, not a legend hunt. Source line from Data only. If a number is not in Data, do not chart it. 7. Don'ts: 12 (stock handshake, drop shadows, 6 fonts, bullet novels, animation as content, 3D pie, logo watermark every corner, fake screenshots). 8. 12-slide skeleton: titles only, mapped to types, using Job. Not the speech. Constraints: - Honor Forbidden and Brand. - Do not invent metrics. - This is slides, not a website design system. - No emojis unless Brand demands them. - Room: if TV at the back, bump title size and avoid thin lines.
