Brand

A modern, graphic, editorial-poster aesthetic — warm and confident — built on alternating cream and burnt orange sections, an amber brand color.

Style Foundations

Visual style: modern, clean, high-contrast
Typography scale: 12/14/16/20/24/32 | Fonts: primary=Chakra Petch, display=Chakra Petch, mono=JetBrains Mono | weights=100, 200, 300, 400, 500, 600, 700, 800, 900
Color palette: primary, neutral, success, warning, danger | Tokens: primary=#CC8800, secondary=#C55221, success=#16A34A, warning=#D97706, danger=#DC2626, surface=#FFFFFF, text=#111827
Spacing scale: 4/8/12/16/24/32

Accessibility

WCAG 2.2 AA, keyboard-first interactions, visible focus states

Writing Tone

concise, confident, helpful

Rules: Do

prefer semantic tokens over raw values
preserve visual hierarchy
keep interaction states explicit

Rules: Don't

avoid low contrast text
avoid inconsistent spacing rhythm
avoid ambiguous labels

Expected Behavior

Follow the foundations first, then component consistency.
When uncertain, prioritize accessibility and clarity over novelty.
Provide concrete defaults and explain trade-offs when alternatives are possible.
Keep guidance opinionated, concise, and implementation-focused.

Guideline Authoring Workflow

Restate the design intent in one sentence before proposing rules.
