Taste Slides: every title is a takeaway

Reads brand-guidelines.md and design-tokens.json. If the environment has a native deck type, or the user asks for .pptx, use that and apply the same narrative and copy rules.

Procedure

1. Intake (infer; ask max 2 questions): purpose, audience and the decision they must make, time limit, desired action at the end, supplied data, delivery mode (live, async, both). Budget 1-2 minutes per content slide.
2. Narrative: pick a structure from references/narratives.md. Open with the answer or the ask (pyramid principle).
3. Outline as titles only: each title a full-sentence takeaway ("Churn fell 18% after the onboarding change"), never a topic label ("Churn"). Read the titles alone: they must tell the whole story. Show this outline before building when the deck has 8+ slides.
4. Archetype per slide from the layout library; one idea, one focal point.
5. Build from templates/deck.html (keyboard, touch, notes, overview, print, reduced motion already wired). Fill tokens, slides, data-notes, chart data.
6. Check the gate below; produce notes.md (talk track, transition, likely question with answer, data source per slide).

Limits

At most 30 words per slide (async: 60), 3 bullets of at most 12 words, 1 chart, 2 fonts and 2 weights. Minimum text 18px at the 1920x1080 artboard; body 28-32px; titles 56-72px. Margins 96px; 12-column grid; whitespace at least 30%.

Charts

Type by question (taste-direction dataviz). Chart.js: responsive: true, maintainAspectRatio: false in a fixed-height box; colors read from CSS variables at init so themes work; labels at least 16px; light horizontal grid only; direct labels; one highlighted series; annotate the takeaway; Intl.NumberFormat; <canvas role="img" aria-label="<takeaway>"> plus a visually hidden data table. Standard mode: pinned CDN version. Portable Mode: vendored file or inline SVG. No data supplied: label as illustrative sample in a footnote and in notes. Never invent metrics, customers, logos or quotes.

Quality gate

• First slide states the answer or ask; last slide asks for one action.
• Titles alone tell the story; each is a takeaway sentence.
• One idea and one focal point per slide; word limits met; 18px minimum.
• Charts match their question, labelled, annotated, accessible, token-colored, real data.
• Keyboard, touch, overview, notes and print-to-PDF work; reduced motion honoured.
• Tokens only; contrast verified; no emoji, no third-party marks; speaker notes and sources included.
