# Visual System

Style name: Flat Finance Cards

## Core DNA

- Crisp white canvas with small chart/dot accents and restrained edge props.
- Dark navy structure, sky-blue processing, emerald approval/growth, and mustard emphasis/action.
- Giant bold geometric Japanese sans-serif; no soft pastel or handwritten headline treatment.
- Beveled dark-navy arrow-shaped subline and takeaway bars with thin electric-blue keylines.
- Rounded white finance cards with subtle gray shadows, colored header tabs, and large readable labels.
- Polished flat invoices, ledgers, folders, calendars, calculators, coins, KPI charts, magnifiers, and approval checks.
- One dominant document pipeline, accounting cycle, shared ledger, rising roadmap, priority matrix, or daily workflow.
- Arrows, clock nodes, document tokens, and checks must explain movement, review, or repeatability.

## Intended Use

経理、請求書処理、月次業務向け。フラットなカード、会計アイコン、カレンダーで堅い業務をわかりやすくする。

## Tone

Make the slide feel like a complete paid-course slide system, not a loose image prompt. It should be clear enough for a lecture, strong enough for thumbnails, and visually consistent across a deck.

## Required Page Architecture

Every output should have:

- One dominant headline.
- One short subline.
- One central metaphor, scene, or diagram.
- Exactly 3 visible label elements unless the user explicitly asks otherwise.
- One bottom takeaway strip, footer, or closing sentence area.

## Style Preservation

Match `assets/reference-slides/style-reference.png` and `samples/contact_sheet.png`.
Preserve the palette, density, line quality, object treatment, typography weight, and visual hierarchy implied by those samples.
Do not copy only the cover slide. Slides 02-10 are also authoritative finished examples of this style's layout system.
If the output looks like a neutral white business template with only the colors changed, it fails.

Cards must behave like operational records. A row of unrelated white rectangles is not this style. Show documents entering, moving through processing, receiving review, and becoming a retained or shared record.

## Avoid

- Generic PowerPoint templates.
- Plain white cards with small icons only.
- Fake URLs, fake QR codes, fake logos, fake dates, fake prices, fake social media UI.
- Tiny unreadable Japanese text.
- Extra decorative microcopy unrelated to the user's content.
- Copying a real brand, creator, app, or character.
- Raw spreadsheet screenshots, invented company/account data, photorealism, 3D, or dark dashboards.
- Equal generic cards with no document pipeline, review logic, or finance-operational meaning.
