## Overview

Simple and efficient flat design landing page for a task management app. Ideal for landing pages, modern websites. AI-ready template. Flat design found its most natural home in productivity software. Not because it was trendy—though it was—but because task management demands visual silence. Every shadow, every gradient, every decorative flourish competes with the one thing that matters: your next action.

Todoist understood this early. Strip the interface to colored dots and clean type. Let priority speak through hue alone. Things took it further—nearly monochrome, obsessively minimal, treating whitespace as a functional element rather than empty real estate. TickTick landed somewhere between: flat foundations with subtle depth cues where hierarchy demanded it. Three apps, three interpretations, one shared conviction that decoration is debt in a tool you open forty times a day.

The productivity-flat lineage runs through Clear, Wunderlist, and into today's Linear and Notion. What connects them isn't aesthetic dogma. It's the recognition that cognitive load is the enemy of getting things done, and every pixel that doesn't serve the task is a pixel working against the user.

- 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

## Implementation Checklist

- ☐ Elementos planos
- ☐ Cores vibrantes/sólidas
- ☐ Tipografia sans-serif limpa
- ☐ Ícones vetoriais simples
- ☐ Micro-interações de feedback de cor

## 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.
