Read the README.md file within this skill, and explore the other available files.

Fenja AI is a "Nordic Editorial" / "Digital Archivist" brand. The design language is quiet, academic, and paper-like — unbleached neutrals, hand-rubbed wood, and five matte "Archival Pigment" accents. No 1px dividers; depth comes from tonal surface shifts. Typography pairs Newsreader (serif, for intent) with Manrope (sans, for execution).

Core files:
- `README.md` — brand context, content fundamentals, visual foundations
- `ICONOGRAPHY.md` — icon approach, Lucide substitution, usage rules
- `colors_and_type.css` — all CSS variables + semantic base styles (`@import` or `<link>` this into every artifact)
- `fonts/` — self-hosted Manrope + Newsreader TTFs
- `assets/` — logos (icon + wordmark, black + white)
- `preview/` — small preview cards for each system concept
- `ui_kits/product/` — reference product implementation (React + JSX)

If creating visual artifacts (slides, mocks, throwaway prototypes, etc), copy `colors_and_type.css` and the needed assets out, then build static HTML files that link the stylesheet. If working on production code, copy assets and read the rules here to become an expert in designing with this brand.

If the user invokes this skill without any other guidance, ask them what they want to build or design, ask some questions, and act as an expert designer who outputs HTML artifacts or production code, depending on the need.

### Non-negotiables
- No 1px solid borders for layout (use tonal surface shifts or 15%-opacity ghost borders)
- No emoji anywhere
- No "tech blue" — only `#5a6d83` Faded Indigo
- No centered hero text — always left-aligned with a strong vertical axis
- Primary CTA: vertical gradient `#785f53 → #6b5348`, radius 12px
- Headlines always Newsreader with `letter-spacing: -0.02em` at display sizes
- One easing (`cubic-bezier(.2, 0, 0, 1)`), three durations (140 / 240 / 420ms), no bounces
- Generous margins — `7rem` lateral padding on desktop hero sections
