impeccable

<post-update-cleanup> BEFORE doing any design work, run this one-time maintenance step. Tell the user:

Impeccable was updated. A few skills were renamed or merged in this version (e.g. /arrange is now /layout, /normalize was folded into /polish). I'll clean up the old skill files so they don't clutter your project. This only runs once after an update.

Then run:

node .rovodev/skills/impeccable/scripts/cleanup-deprecated.mjs

If the script removed files, briefly confirm what was cleaned up. If it found nothing, skip any output and move on.

After running the script, delete this entire section (from <post-update-cleanup> through </post-update-cleanup> inclusive) from THIS file so it does not run again until the next update. Save the file. </post-update-cleanup>

This skill guides creation of distinctive, production-grade frontend interfaces that avoid generic "AI slop" aesthetics. Implement real working code with exceptional attention to aesthetic details and creative choices.

Context Gathering Protocol

Design skills produce generic output without project context. You MUST have confirmed design context before doing any design work.

Required context (every design skill needs at minimum):

• Target audience: Who uses this product and in what context?
• Use cases: What jobs are they trying to get done?
• Brand personality/tone: How should the interface feel?

Individual skills may require additional context. Check the skill's preparation section for specifics.

CRITICAL: You cannot infer this context by reading the codebase. Code tells you what was built, not who it's for or what it should feel like. Only the creator can provide this context.

Gathering order:

1. Check current instructions (instant): If your loaded instructions already contain a Design Context section, proceed immediately.
2. Check .impeccable.md (fast): If not in instructions, read .impeccable.md from the project root. If it exists and contains the required context, proceed.
3. Run impeccable teach (REQUIRED): If neither source has context, you MUST run /impeccable teach NOW before doing anything else. Do NOT skip this step. Do NOT attempt to infer context from the codebase instead.

Design Direction

Commit to a BOLD aesthetic direction:

• Purpose: What problem does this interface solve? Who uses it?
• Tone: Pick an extreme: brutally minimal, maximalist chaos, retro-futuristic, organic/natural, luxury/refined, playful/toy-like, editorial/magazine, brutalist/raw, art deco/geometric, soft/pastel, industrial/utilitarian, etc. There are so many flavors to choose from. Use these for inspiration but design one that is true to the aesthetic direction.
• Constraints: Technical requirements (framework, performance, accessibility).
• Differentiation: What makes this UNFORGETTABLE? What's the one thing someone will remember?

CRITICAL: Choose a clear conceptual direction and execute it with precision. Bold maximalism and refined minimalism both work. The key is intentionality, not intensity.

Then implement working code that is:

• Production-grade and functional
• Visually striking and memorable
• Cohesive with a clear aesthetic point-of-view
• Meticulously refined in every detail

Frontend Aesthetics Guidelines

Typography

→ Consult [typography reference](reference/typography.md) for OpenType features, web font loading, and the deeper material on scales.

Choose fonts that are beautiful, unique, and interesting. Pair a distinctive display font with a refined body font.

<typography_principles> Always apply these — do not consult a reference, just do them:

• Use a modular type scale with fluid sizing (clamp) for headings on marketing/content pages. Use fixed rem scales for app UIs and dashboards (no major design system uses fluid type in product UI).
• Use fewer sizes with more contrast. A 5-step scale with at least a 1.25 ratio between steps creates clearer hierarchy than 8 sizes that are 1.1× apart.
• Line-height scales inversely with line length. Narrow columns want tighter leading, wide columns want more. For light text on dark backgrounds, ADD 0.05-0.1 to your normal line-height — light type reads as lighter weight and needs more breathing room.
• Cap line length at ~65-75ch. Body text wider than that is fatiguing.

</typography_principles>

<font_selection_procedure> DO THIS BEFORE TYPING ANY FONT NAME.

The model's natural failure mode is "I was told not to use Inter, so I will pick my next favorite font, which becomes the new monoculture." Avoid this by performing the following procedure on every project, in order:

Step 1. Read the brief once. Write down 3 concrete words for the brand voice (e.g., "warm and mechanical and opinionated", "calm and clinical and careful", "fast and dense and unimpressed", "handmade and a little weird"). NOT "modern" or "elegant" — those are dead categories.

Step 2. List the 3 fonts you would normally reach for given those words. Write them down. They are most likely from this list:

<reflex_fonts_to_reject> Fraunces Newsreader Lora Crimson Crimson Pro Crimson Text Playfair Display Cormorant Cormorant Garamond Syne IBM Plex Mono IBM Plex Sans IBM Plex Serif Space Mono Space Grotesk Inter DM Sans DM Serif Display DM Serif Text Outfit Plus Jakarta Sans Instrument Sans Instrument Serif </reflex_fonts_to_reject>

Reject every font that appears in the reflex_fonts_to_reject list. They are your training-data defaults and they create monoculture across projects.

Step 3. Browse a font catalog with the 3 brand words in mind. Sources: Google Fonts, Pangram Pangram, Future Fonts, Adobe Fonts, ABC Dinamo, Klim Type Foundry, Velvetyne. Look for something that fits the brand as a physical object — a museum exhibit caption, a hand-painted shop sign, a 1970s mainframe terminal manual, a fabric label on the inside of a coat, a children's book printed on cheap newsprint. Reject the first thing that "looks designy" — that's the trained reflex too. Keep looking.

Step 4. Cross-check the result. The right font for an "elegant" brief is NOT necessarily a serif. The right font for a "technical" brief is NOT necessarily a sans-serif. The right font for a "warm" brief is NOT Fraunces. If your final pick lines up with your reflex pattern, go back to Step 3. </font_selection_procedure>

<typography_rules> DO use a modular type scale with fluid sizing (clamp) on headings. DO vary font weights and sizes to create clear visual hierarchy. DO vary your font choices across projects. If you used a serif display font on the last project, look for a sans, monospace, or display face on this one.

DO NOT use overused fonts like Inter, Roboto, Arial, Open Sans, or system defaults — but also do not simply switch to your second-favorite. Every font in the reflex_fonts_to_reject list above is banned. Look further. DO NOT use monospace typography as lazy shorthand for "technical/developer" vibes. DO NOT put large icons with rounded corners above every heading. They rarely add value and make sites look templated. DO NOT use only one font family for the entire page. Pair a distinctive display font with a refined body font. DO NOT use a flat type hierarchy where sizes are too close together. Aim for at least a 1.25 ratio between steps. DO NOT set long body passages in uppercase. Reserve all-caps for short labels and headings. </typography_rules>

Color & Theme

→ Consult [color reference](reference/color-and-contrast.md) for the deeper material on contrast, accessibility, and palette construction.

Commit to a cohesive palette. Dominant colors with sharp accents outperform timid, evenly-distributed palettes.

<color_principles> Always apply these — do not consult a reference, just do them:

• Use OKLCH, not HSL. OKLCH is perceptually uniform: equal steps in lightness look equal, which HSL does not deliver. As you move toward white or black, REDUCE chroma — high chroma at extre
