## About

# Geopolitical Data Briefing

## Design Overview

This design system evokes a printed strategic briefing document projected onto a screen. The warm parchment background (#f5f3ef) reduces glare compared to pure white, making it comfortable for conference-room projection and long reading sessions. Typography is rooted in editorial tradition — Georgia for authoritative headlines, Palatino for readable body copy, and Courier New for data labels — creating a "research report" atmosphere. The three-accent palette (navy for the US, crimson for China, gold for insight callouts) introduces controlled color only where it carries semantic weight, keeping the overall impression sober, credible, and intellectually rigorous.

## Hard Rules

### Canvas
- Slide dimensions: 1920×1080px, scaling responsively via CSS transform
- Background: **#f5f3ef** — a warm parchment off-white that prevents eye strain on projected screens (pure #FFFFFF creates glare on large displays)
- Slide padding: **56px top/bottom, 72px left/right** on all content slides except the title slide

### Color Palette (Exact Values)
| Role | Hex | Usage |
|------|-----|-------|
| Page background | `#f5f3ef` | All slide backgrounds |
| Card/container background | `#faf9f7` | Cards, stat boxes, source items — slightly lighter than page for subtle elevation |
| Primary text | `#1a1a1a` | Headlines, body text, KPI values |
| Secondary text | `#5c5c5c` | Subtitles, descriptions, chart labels |
| Muted text | `#7a7a7a` | Meta labels, axis labels, section overlines |
| Faded text | `#b0aaa0` | Slide numbers, inactive dots, tertiary chrome |
| Border / divider | `#e0ddd6` | Card borders, section dividers, timeline lines, bar tracks |
| Subtle inner border | `#eeeae4` | Row separators within cards and lists |
| Navy accent (US) | `#1a3a5c` | US bar fills, US section headers, US timeline dots, strong text highlights, navigation hover |
| Crimson accent (China) | `#8b1a1a` | China bar fills, China section headers, China timeline dots, secondary emphasis |
| Gold accent (insight) | `#d4a84b` | Key insight callouts, the title slide decorative line, progress bar fill, takeaway numbers, data highlights |
| Bar track background | `#e8e4dc` | Unfilled portion of bar charts (slightly darker than page to give the track definition) |
| Mini-bar neutral | `#d0cdc6` | Placeholder bar segments in mini-charts |
| Inactive dot | `#d0cdc6` | Navigation dot default state |
| Arrow between flow nodes | `#c0bbb2` | Flow diagram connector arrows |

### Font Role Summary
- **Georgia** — All headlines, KPI values, comparison values, takeaway numbers, comparison headers, card titles. Conveys authority and editorial weight.
- **Palatino** — All body copy, subtitles, descriptions, timeline content. Provides readability with a slightly humanist warmth.
- **Segoe UI** — All labels, overlines, chart titles, KPI labels, bar labels, comparison row labels. The sole sans-serif provides structural contrast and legibility at small sizes.
- **Courier New** — All data values (bar values, slide numbers, source items, timeline years, title meta). The monospace font signals data precision and evokes research-report aesthetics.

### Spacing & Layout
- Content slides use a **slide-header + slide-body** pattern with a 1px `#e0ddd6` border separating them
- Slide header bottom border has **20px padding-bottom** and **28px margin-bottom**
- Slide body uses CSS Grid with **24px gap** as the default rhythm unit
- Cards use **28px 32px** internal padding with **0 border-radius** (sharp corners signal seriousness)
- Grid helpers: `.grid-2` (1fr 1fr, 24px gap), `.grid-3` (1fr 1fr 1fr, 24px gap), `.grid-4` (1fr 1fr 1fr 1fr, 20px gap), `.grid-12` (repeat 12, 20px gap)
- The thin rule divider (`.rule-thin`) is **1px #e0ddd6** used between sections
- Margin utility classes: `.mt-8`, `.mt-16`, `.mt-24`, `.mb-8`, `.mb-16`

### Cards
- Background: `#faf9f7` (slightly lighter than page)
- Border: 1px solid `#e0ddd6`
- Border-radius: **0** (never rounded — sharp corners are a rule of this system)
- Padding: 28px 32px

### Bar Charts
- Bar track: height 20px, background `#e8e4dc`, no border-radius (standard bar) or 4px border-radius (patent bars)
- Bar fill colors: `.us` = `#1a3a5c`, `.cn` = `#8b1a1a`, `.gold` = `#d4a84b`, neutral = `#b0aaa0`
- Bar row grid: 100px label / 1fr track / 80px value (with 12px gap), or compact 40px / 1fr / 40px for sector bars
- Bar labels: Segoe UI 18px `#5c5c5c`, right-aligned
- Bar values: Courier New 16px `#1a1a1a`, right-aligned
- Transition: `width 0.6s ease` (standard) or `0.8s ease` (patent bars)

### Mini Bar Charts (inside KPI cards)
- Container: display flex, align-items flex-end, height 80px, gap 4px
- Individual bars: flex 1, background `#e0ddd6`, border-radius 2px 2px 0 0 (slight rounding to distinguish from full charts)
- Semantic colors applied via `.us`, `.cn`, `.gold` classes

### Navigation Chrome
- Progress bar: fixed top, 3px height, track `#e0ddd6`, fill `#d4a84b`
- Navigation buttons: fixed bottom, 48×48px, background `#faf9f7`, border 1px `#e0ddd6`, Courier New 22px
- Button hover: background becomes `#1a3a5c`, text becomes white, border becomes `#1a3a5c`
- Dot indicators: 10px circles, default `#d0cdc6`, active `#1a3a5c` (expands to 28px wide pill), hover `#b0aaa0`
- Slide counter: fixed bottom center, Courier New 16px, `#7a7a7a`
- Edge click zones: fixed left/right 15% width transparent overlays for tap navigation

### Animation
- Fade-in animation: `fadeIn` keyframe — translates 12px up while fading opacity 0→1, 0.5s duration, ease timing
- Staggered delays: `.anim-delay-1` through `.anim-delay-5` (0.1s increments)
- Bar fill transitions: 0.6s ease (standard), 0.8s ease (patent bars)

## Banned

1. **Never use rounded corners on cards, containers, or major UI elements.** Sharp 0px border-radius is a defining characteristic. The sole exception is mini-bar tops (2px) and navigation dots/pills, which are UI chrome, not content containers.
2. **Never use pure white (#FFFFFF) or pure black (#000000) as content surface colors.** The system lives in warm off-whites. Pure black is only used for the HTML/body background behind the scaled presentation wrapper — never inside slides.
3. **Never use font-weights above 400 on Georgia headlines.** The system achieves hierarchy through size and letter-spacing, not boldness. Weight 700 appears only on Courier New timeline years, comparison row values, and bar-label value spans — never on Georgia or Palatino headings.
4. **Never introduce colors outside the defined palette.** The five semantic colors (#1a3a5c navy, #8b1a1a crimson, #d4a84b gold, #e0ddd6 border, #f5f3ef background) and their neutral derivatives form a closed system. No blues other than navy, no reds other than crimson, no greens, no purples.
5. **Never center-align body text or card content.** Text alignment is left by default. The only centered elements are: KPI cards, the closing slide, flow nodes, and compute stats — all of which are small contained modules, not running text.
6. **Never use sans-serif for body copy or headlines.** Segoe UI is strictly for labels, overlines, chart titles, and UI chrome. All readable prose must be Georgia or Palatino.

## Slide Archetypes

### Archetype 1 — Title Slide (Slide 1)
- **Structure**: Full-bleed parchment canvas with a 6px navy bar across the top edge. Content is vertically centered in a flex column with 80px/100px padding.
- **Elements (in order)**:
  - Gold decorative line: 80px wide, 3px tall, `#d4a84b`, margin-bottom 32px
