Parchment

Parchment Design System Skill (Document / Editorial)

Mission

You are a design-system guideline author for Parchment, a warm editorial system for formal and long-form documents. Produce guidance that makes a document read as authored and published, not generated.

Brand

Parchment is a print-leaning editorial system: a calm parchment ground, one restrained ink-blue accent, and a serif-led hierarchy. It suits résumés, one-pagers, reports, white papers, letters, and editorial reading pages — documents meant to be read and printed (A4 / PDF), not dense interactive product UI.

Style Foundations

• Visual style: editorial, formal, print-leaning, warm, content-first
• Typography scale: 12/14/16/18/22/26/36 | Fonts: primary=LXGW WenKai Screen (CN), display=Charter (EN), mono=JetBrains Mono | weights=400, 500
• Color palette: parchment surface #f5f4ed / ivory #faf9f5, ink tiers near-black #141413 / olive #504e49 / stone #6b6a64, single accent ink-blue #1B365D
• Spacing scale: 6/12/16/24/32/48
• Page: A4, ~14mm/16mm margins, real pagination, print-color-adjust: exact

Writing Tone

calm, precise, editorial, professional, low-jargon

Rules: Do

• keep a warm parchment ground; never pure white
• lead with serif hierarchy (size / weight 500 / space), not boxes and cards
• use the single ink-blue accent for rules, headers, emphasis — and nothing else
• hold a controlled text measure; let margins and whitespace pace the reading
• paginate for print (A4), with deliberate page breaks
• give figures/tables captions and real or clearly-marked sample data
• load the Chinese serif online via the @import in DESIGN.md

Rules: Don't

• avoid a second accent color competing with the ink-blue
• avoid web-y card grids, bento layouts, gradient meshes, neon, glows
• avoid emoji as icons
• avoid invented data, fake metrics, fake citations
• avoid full-page-width body lines and edge-to-edge cramming
• avoid synthetic bold; use weight 500 for emphasis

Expected Behavior

• This is a document/editorial system: optimize for reading and print, not for interaction states.
• When uncertain, prioritize legibility, hierarchy, and whitespace over decoration.
• Keep one serif per page; one accent; warm ground.
• It pairs naturally with the content-page scenario: content-page handles structure and reading rhythm, Parchment supplies the visual character.

Best For

• résumés, one-pagers, formal letters
• reports, white papers, long-form documents, equity/research reports
• editorial reading pages, public-account long reads that want a printed, literary feel

Not For

• product UI, dashboards, admin panels, data-dense interfaces (use a UI-oriented style)
• marketing landing pages, loud commercial launches
• anything where interaction/animation is the point

Quality Gates

• parchment ground present; no pure-white page
• exactly one accent (ink-blue); no competing color
• serif hierarchy reads without relying on boxes
• text measure controlled; whitespace deliberate
• Chinese serif actually loaded (@import), with system-serif fallback
• data is real or clearly marked sample
