Renn F 22572fdee1 chore(prompts): reflow hard-wrapped prose to satisfy the markdown gate
A's vendored fable.md and C's design-bar prose went in hard-wrapped, which
fails make quality's reflow-check (the no-hard-wrap gate). Reflowed to one line
per paragraph via scripts/reflow_md.py. reflow-check now clean.

  • Hooks for state and effects
  • TypeScript strict mode
  • Responsive design
  • Accessibility (WCAG compliance)

Design bar

Distilled from Leonxlnx/taste-skill (MIT) — an anti-slop frontend framework: fixes generic layout, default fonts, and motion-for-its-own-sake. A taste layer on top of your stack, not a replacement for it.

The three dials

State your read in your decision note before you build — don't silently default.

  • DESIGN_VARIANCE (1-10): 1-3 predictable (symmetric grid, equal paddings) · 4-7 offset (overlaps, mixed aspect ratios) · 8-10 asymmetric (masonry, fractional grids, bold negative space). Always collapses to single-column below md:.
  • MOTION_INTENSITY (1-10): 1-3 static (hover/active only) · 4-7 fluid transform/opacity transitions · 8-10 scroll-driven choreography. Above 3, prefers-reduced-motion support is mandatory.
  • VISUAL_DENSITY (1-10): 1-3 airy/gallery-like · 4-7 standard app spacing · 8-10 packed/tabular (tight paddings, no card boxes, monospace/tabular numerals).
  • Defaults: dense product UI (admin panels, dashboards, data tables) → 2-3 / 2-3 / 7-8. Landing/marketing/portfolio surface → 7 / 6 / 4 (SaaS baseline; push variance/motion higher for agency/creative briefs).

Typography & hierarchy

  • Hierarchy comes from weight + size + color + whitespace, not just "make it bigger."
  • Body copy: cap line length around 65-75ch.
  • One accent color per project; WCAG AA contrast minimum (4.5:1 body, 3:1 large text) — audit every button, form label, and ghost-button-over-photo before shipping.
  • Numeric/data-heavy UI (tables, metrics, IDs): tabular figures, not proportional digits that jiggle column widths.
  • A project's existing font/color/radius choice is a decision, not a default to silently swap because this bar suggests otherwise — a real change gets its own task.

Spacing & layout

  • Consistent vertical rhythm across siblings: aligned card/column baselines, CTAs bottom-aligned across a row regardless of copy length above them.
  • Grid over flexbox-percentage-math for multi-column layout.
  • min-h-[100dvh], never h-screen, for full-bleed sections (mobile viewport jump).
  • Cards only when elevation communicates real hierarchy — otherwise a divider or spacing does the job. One corner-radius scale, one shadow tint, per project.
  • Avoid the reflexive three-equal-cards-in-a-row layout; vary composition instead.

Motion

  • Every animation needs a one-sentence justification: hierarchy, storytelling, feedback, or state change. "It looked cool" is not one.
  • Animate transform/opacity only — never top/left/width/height, never a raw scroll event listener (useScroll/IntersectionObserver/ ScrollTrigger/CSS scroll-driven animation instead).
  • Loading/empty/error states are part of the design, not an afterthought — skeletons matching the final layout, not generic spinners.

AI tells to avoid

In anything you write for an end user — copy, demo data, layout — not your own commits/journal/PR text:

  • No em-dash in product copy you author: headlines, labels, button text, placeholders.
  • No "Jane Doe" / "Acme Corp" / suspiciously-round numbers in placeholder content — specific-sounding names, organic numbers.
  • No filler verbs ("Elevate", "Seamless", "Unleash", "Next-Gen").
  • No default AI-purple glow, no pure #000/#fff. One icon family per project.

Where this applies

Building or touching the RoboCo control panel or any dense admin/dashboard surface: work within the project's existing design system for structural chrome (nav, tables, forms, theme tokens); apply the rules above on top of it. taste-skill's landing-page-specific hard caps (hero word/line limits, eyebrow-per-3-sections, bento cell-count, marquee-max-one) are for marketing/landing/portfolio surfaces, not dashboards. Check the task brief if you're unsure which mode you're in.
