## Overview

Dark portfolio with animated loading screen (2.7s): counter 000→100 via rAF, rotating words with AnimatePresence, gradient progress bar (#89AACC to #4E85BF) with glow. Ideal for portfólios de desenvolvedores, designers criativos, freelancers fullstack, sites pessoais premium. AI-ready template. The dark cinematic hero owes its DNA to two parallel lineages: demo scene culture and film title sequences. In the early 2000s, Flash portfolios weaponized loading screens — turning wait time into theater. Designers like Joshua Davis and 2Advanced Studios proved that the entrance *was* the portfolio. The loading bar became a stage curtain. When Flash died, that theatrical energy went dormant until GSAP and WebGL revived it around 2016.

The second thread is Saul Bass through Kyle Cooper through Ash Thorp. Title sequences taught us that mood precedes content. A dark field with precise typography and choreographed motion tells the viewer: this person controls every pixel. The dark portfolio hero isn't decoration — it's a credibility signal. It says you understand timing, contrast, and restraint before anyone scrolls.

Today these heroes dominate Awwwards and creative studio sites because they solve a real problem: establishing artistic authority in under three seconds. The darkness isn't aesthetic preference — it's functional. It kills distraction and forces the eye to follow motion.

## Do's and Don'ts

- No pure black (#000000) — use off-black or charcoal variants
- No oversaturated accent colors (saturation cap: 80%)
- No 3-column equal-width feature layouts — use zig-zag or asymmetric grid
- No `h-screen` — use `min-h-[100dvh]`
- No AI copywriting clichés: "Elevate", "Seamless", "Unleash", "Next-Gen"
- No broken external image links — use picsum.photos or inline SVG
- No generic lorem ipsum in demos

## Execution Rules

1. Strictly follow the defined visual style.
2. Use high-quality inline SVG icons (Heroicons or Lucide style) — NEVER use emojis as icons.
3. Add `cursor-pointer` and smooth `hover` states (transition-all) on all interactive elements.
4. Required Page Structure:
   - Navbar (Logo + Links + CTA)
   - Hero Section (Impactful Headline + Subtitle + 2 buttons + 3D/Abstract visual element via CSS)
   - Features (3 cards with icons)
   - Testimonials (3 cards)
   - Pricing (3 tiers, highlight the middle one)
   - Final CTA
   - Full Footer with social links, privacy policy, terms of use, contact and SEO links.
5. All text content must be in English.
6. The visual must be CLEARLY distinct — do not create a "default Bootstrap" design. Force the use of the provided design system variables.
7. Use `<style>` tags in the head for custom classes (especially for complex backdrop-filter effects and animations) that Tailwind CDN doesn't cover.
8. Full Responsiveness: Layout must adapt perfectly to Mobile, Tablet and Desktop (vertical stack on mobile).
9. Include basic SEO, Viewport and Open Graph meta tags in `<head>`.
10. Footer must contain: Copyright 2026, Secondary navigation links and Social media icons.
11. Make the creative decisions needed to deliver the complete, functional result now.
