This skill guides creation of frontend interfaces for the Fables & Sagas D&D Solo app. All output must integrate seamlessly with the existing codebase and its dark medieval fantasy aesthetic.

Tech Stack

• Framework: Next.js 16 with React 19, TypeScript
• Styling: Tailwind CSS v4 with DaisyUI v5
• State: Zustand (useDnDStore from @/stores/useStore)
• Icons: lucide-react (primary), @mdi/react + @mdi/js (supplemental)
• Toasts: sonner (dark theme, custom styled — see layout.tsx)
• Lists: react-virtuoso for virtualized scrolling
• Markdown: react-markdown
• Fonts loaded via next/font/google:
  • MedievalSharp — display/headings (import from @/app/components/medievalFont)
  • EB_Garamond — secondary display
  • Geist / Geist_Mono — body text (CSS variables --font-geist-sans, --font-geist-mono)

Theme: "fables"

DaisyUI custom theme (data-theme="fables") defined in src/app/globals.css:

Always use DaisyUI semantic tokens (text-primary, bg-base-200, btn-primary, etc.) instead of hardcoded colors.

Custom Tailwind Utilities

Defined in src/app/globals.css:

• bg-login-vignette — radial gradient overlay for cinematic scenes
• bg-gradient-radial, bg-gradient-conic — custom gradient utilities
• .animate-fade-in-up, .animate-fade-in-up-delay-1/2/3 — staggered entrance animations
• .text-glow-gold — gold text-shadow glow effect for dramatic headings

Component Patterns

Follow these conventions from existing code:

• "use client" directive on all interactive components
• DaisyUI classes for base components: btn, input, input-bordered, modal, drawer, card, badge, tooltip
• Opacity modifiers for subtle layering: bg-base-200/50, border-primary/15, text-base-content/30
• Section headers use medievalFont.className with gold decorative horizontal rules (see SectionHeader.tsx pattern)
• Modals use fixed overlay with bg-black bg-opacity-50, centered card with border-2
• Inputs use: input input-bordered w-full bg-base-200/50 border-primary/15 text-base-content placeholder:text-base-content/30 focus:border-primary/40 focus:outline-none
• Drawers slide from right with backdrop blur

Aesthetic Direction

This app has a dark medieval fantasy aesthetic — think weathered parchment text on near-black backgrounds, gold filigree accents, and deep crimson highlights. The tone is immersive and atmospheric, like opening an ancient tome by candlelight.

When designing new components:

• Lean into the dark + gold contrast
• Use medievalFont for section titles and dramatic text
• Apply subtle opacity and blur for depth (backdrop-blur-sm, /50 opacity modifiers)
• Use staggered animate-fade-in-up for page entrances
• Add text-glow-gold sparingly for emphasis on hero elements
• Keep backgrounds dark (base-100, base-200) with gold (primary) as the accent color
• Borders should be subtle: border-primary/15 to border-primary/40
