Tightened Slide

Use this workflow when a user asks for a Tightened Slide deck, horizontal swipe presentation, HTML slide deck, launch deck, analysis deck, framework deck, product deck, or data-driven talk.

Operating Assumptions

  • This is a Tightened Slide only system.
  • The output is a static HTML deck, normally index.html, with an adjacent images/ folder.
  • The template is assets/template.html.
  • Body slides must use registered S01 to S22 layouts.
  • The validator is required before delivery.
  • Supported language modes are English and Korean.

Step 1: Clarify Only What Matters

If the user provides a complete outline and assets, proceed. If key inputs are missing, ask at most three questions:

1. Audience and presentation setting. 2. Target duration or page count. 3. Source material, language mode, required images/data, and hard constraints.

If the theme is unspecified, default to International Klein Blue from references/themes.md. If the language mode is unspecified, default to English.

Step 2: Prepare The Deck

Create the target folder and image folder:

mkdir -p path/to/deck/images
cp assets/template.html path/to/deck/index.html

Immediately replace the <title> placeholder in index.html.

Set the language mode on the root element:

<html lang="en" data-language="en">

or:

<html lang="ko" data-language="ko">

Korean mode uses the template font stack SUIT, Pretendard, Noto Sans KR, and Noto Sans before falling back to Inter and system sans fonts.

If the deck must work offline with local animation fallback, keep assets/motion.min.js reachable from the copied HTML path or accept the CDN fallback built into the template.

Step 3: Preflight

Before writing slide markup:

  • Read the template <style> block.
  • Read references/layout-lock.md.
  • Read the relevant skeletons in references/layouts.md.
  • Confirm every class you plan to use exists in the template.
  • Do not invent global classes. Use inline styles only for page-specific tuning.

Create a planning table before coding:

page -> data-layout -> reason -> image slot

For 7-8 page decks, use at least six different Sxx layouts. For 10+ page decks, use at least eight.

Step 4: Pick Layouts

Use the registered layout set:

  • S01 Index Cover
  • S02 Vertical Timeline + KPI
  • S03 Split Statement
  • S04 Six Cells
  • S05 Three Layers
  • S06 KPI Tower
  • S07 Horizontal Bar
  • S08 Duo Compare
  • S09 Dot Matrix Statement
  • S10 Split Closing
  • S11 Horizontal Timeline
  • S12 Manifesto + Ink Banner
  • S13 Three Forces
  • S14 Loop Form
  • S15 Matrix + Hero Stat
  • S16 Multi-card Brief
  • S17 System Diagram
  • S18 Why Now
  • S19 Four Cards
  • S20 Stacked KPI Ledger
  • S21 Tech Spec Sheet
  • S22 Image Hero

Use S08 + Tightened Map Component for maps, routes, city relationships, location networks, or historical movement pages.

Use S22 for one large image. Use S15 or S16 adaptations for multiple images. Do not create unregistered image split or evidence wall layouts.

Step 5: Apply The Visual System

Hard rules:

  • One accent color per deck.
  • No gradients, shadows, rounded cards, glass, neon, 3D, or decorative borders.
  • Large type uses light weights: 200 or 300.
  • Body text uses restrained weights and clear hierarchy.
  • Large sizes use font-size:min(Xvw,Yvh) with Y >= X * 1.6.
  • Headings sit on the left/top content axis unless using registered statement/split layouts.
  • Kicker text sits above the title, not beside it.
  • .canvas-card already has horizontal padding; do not add another 5vw padding layer inside it.
  • Keep all captions, labels, and footnotes above the bottom navigation safe area.
  • SVG may draw geometry only; visible labels must be HTML.

Language rules:

  • English mode uses concise sentence case titles and direct body copy.
  • Korean mode uses short Korean titles, compact body lines, and consistent product terms.
  • Diagram labels and generated-image text must match the chosen language mode.

Step 6: Image Flow

If images are needed:

  • Ask before generating new images.
  • Choose the layout slot before writing the prompt.
  • Use references/image-prompts.md.
  • Save generated or provided images in images/.
  • Name images {page}-{semantic-name}.{ext}.
  • Add data-image-slot to every local image.

Slot defaults:

  • S22: s22-hero-21x9
  • S15: s15-grid-21x9 or s15-grid-16x10
  • S16: s16-brief-21x9 or s16-brief-16x10

Step 7: Validate

Run:

node scripts/validate-deck.mjs path/to/index.html

Fix every error. Warnings require visual review.

Then open the deck in a browser and inspect:

  • title alignment
  • type weight
  • spacing between title and body
  • image crop and image slot fit
  • captions and footnotes above navigation
  • ESC index visibility
  • B static mode

Use references/checklist.md as the delivery checklist.
