+# Design System Inspired by Totality Festival
+
+> Category: Themed & Unique
+> Surface: web
+> A cosmic-premium, glassmorphic dark system that captures the visceral awe of a solar eclipse — obsidian surfaces, amber "corona" highlights, and cyan atmospheric accents.
+
+## 1. Visual Theme & Atmosphere
+
+"Cosmic Premium" — the visceral tension and awe of a solar eclipse. The aesthetic blends the stark mystery of deep space with the explosive brilliance of the solar corona. Surfaces appear as translucent obsidian slabs floating over nebula-like gradients. High-energy amber accents represent the "diamond ring" flash — they make the interface feel luminous and alive rather than heavy or muted.
+
+- **Visual style:** dark, glassmorphic, cinematic
+- **Color stance:** obsidian neutral, amber corona accent, cyan atmospheric
+- **Design intent:** Keep outputs recognizable as a premium festival / creator product; use radial gradients for backgrounds to simulate the circular nature of the eclipse.
+
+## 2. Color
+
+- **Primary:** `#fff6df` — Amber / white-gold, the solar corona and "diamond ring" flash. Used for critical CTAs and high-importance highlights.
+- **Primary Container:** `#ffd700` — Pure corona gold. Reserved for the single most important highlight on a screen.
+- **Secondary:** `#bdf4ff` — Soft cyan, the atmospheric thinning and ethereal glow of the sky during totality. Used for interactive states and secondary emphasis.
+- **Secondary Container:** `#00e3fd` — Vivid cyan for interactive ambient glow rims.
+- **Tertiary:** `#fcf3ff` — Faint lavender-white for subtle tinted highlights.
+- **Tertiary Container:** `#e7d1ff` — Deep indigo haze, celestial badges.
+- **Surface:** `#121318` — Obsidian / near-black foundation.
+- **Surface Container:** `#1e1f25` — Slightly elevated obsidian for cards.
+- **Surface Container High:** `#292a2f` — Elevated panels, active states.
+- **Text:** `#e3e1e9` — Warm off-white for primary body copy and headlines.
+- **Text Muted:** `#d0c6ab` — Warm parchment tone for metadata and labels.
+- **Outline:** `#999077` — Low-contrast warm gray for hairline borders.
+
+- Favor Primary (#fff6df) and Primary Container (#ffd700) for the "corona flash" moments — max 3 per screen.
+- Use Secondary (#bdf4ff / #00e3fd) for interactive states, never for decorative flourishes.
+- Surfaces stack as semi-transparent glass: `rgba(255, 255, 255, 0.05-0.1)` with `backdrop-filter: blur(20px)` and a 1px `rgba(255, 255, 255, 0.1)` inner border to simulate light refraction.
+
+## 3. Typography
+
+A dual-font strategy to balance cinematic impact with utility.
+
+- **Display / Headings:** Space Grotesk — geometric, technical, futuristic-astronomical tone. Tight letter spacing (`-0.02em` to `-0.04em`) on large headings to feel "locked" and monumental.
+- **Body / Long-form:** Inter — neutral, highly legible in low-light environments.
+- **Labels:** Space Grotesk with wide tracking (`0.1em`) and uppercase, to read as "coordinates" or "readouts" rather than UI chrome.
+
+Apply a subtle text-shadow or low-opacity primary-colored glow to `headline-xl` elements on the darkest backgrounds for a truly cinematic feel — radiant, not static.
+
+## 4. Layout & Spacing
+
+- **Grid:** 12-column fixed grid on desktop with generous outer margins (64–80px) to simulate the isolation of a celestial body in the void. Fluid model on mobile with 16px margins.
+- **Rhythm:** 8px base unit. Internal component spacing tight (8 / 16px); external section margins wide (64 / 80px) to create distinct "islands" of content.
+- **Max width:** 1280px for content containers.
+- **Negative space is a feature, not a cost.** Prefer breathing room over density.
+
+## 5. Elevation & Depth
+
+Depth is achieved through **glassmorphism** and light-based layering — not traditional drop shadows.
+
+- **Level 1 (Base):** Deep obsidian surface with an optional radial gradient vignette in `#1a1b21` → `#121318`.
+- **Level 2 (Panels):** Semi-transparent surfaces at `rgba(52, 52, 58, 0.2)` with `backdrop-filter: blur(20px)` and a 1px inner stroke at `rgba(255, 255, 255, 0.1)` to simulate refraction on a glass edge.
+- **Level 3 (Interactive / Active):** An **ambient glow** — a soft, diffused shadow tinted with Secondary (`#00e3fd`) or Primary Container (`#ffd700`), creating the impression of light bleeding from behind the object.
+
+## 6. Shapes
+
+Shape language is **soft-technical**. Geometric overall, but small corner radii soften aggression.
+
+- **Buttons, inputs:** `rounded-lg` (8px).
+- **Cards, featured containers:** `rounded-xl` (12px).
+- **Badges, pills:** `rounded-full`.
+- **Decorative elements:** circles and perfect arcs are encouraged to mirror the orbital / eclipse theme.
+
+## 7. Components
+
+- **Primary button:** Amber fill on obsidian, with a luminous amber glow on hover (mimics the diamond-ring flash). Space Grotesk label, uppercase, `0.1em` tracking.
+- **Secondary button:** Transparent fill, cyan outline and label — suggests the sky's transition during totality.
+- **Glass card (level 2):** `rgba(52,52,58,0.2)` + 20px blur + 1px inner white stroke + generous internal padding.
+- **Input field:** Anchored in the deepest surface (`#0d0e13`) for maximum contrast; cyan border on focus.
+- **Badges:** Pill-shaped with the tertiary container color; reserved for "celestial" metadata (status, live indicators).
+
+## 8. Do's & Don'ts
+
+- **Do** use Primary Container (`#ffd700`) no more than 3 times per screen — it's the flash, not the background.
+- **Do** pair large Space Grotesk headlines with a subtle primary-colored glow on dark surfaces.
+- **Do** tint shadows and glows with Primary or Secondary — never use pure gray shadows.
+- **Don't** use solid opaque fills for cards — break the glass illusion.
+- **Don't** combine amber and cyan glows on the same element — choose one depending on state (amber = highlight / CTA; cyan = interactive / focus).
+- **Don't** use sharp 0-radius corners except for data tables where structure outweighs warmth.
