Redesign Key Features section with Split Narrative layout

[Copilot]

The Key Features section lacked visual hierarchy and used technical copy instead of value-focused messaging. Implemented a Split Narrative layout pattern with alternating left-right sections, updated copy, and added visual polish.

Changes

Layout Structure

Split Narrative pattern with 4 full-width alternating rows:

• Row 1: Content left (StyloMetric DNA) + Visual right
• Row 2: Visual left + Content right (Hybrid ML Architecture)
• Row 3: Content left (Explainable AI) + Visual right
• Row 4: Visual left + Content right (Real-Time Accuracy)

Each feature occupies a full-width section with 50-50 content/visual split on desktop, creating strong page rhythm and natural storytelling flow.

Copy Updates

All descriptions rewritten for product value vs. technical details:

// Before
<p>Combines 1D-CNN pattern recognition with Random Forest explainability...</p>

// After  
<p>Fuses neural networks with linguistic intelligence for real-time, interpretable results.</p>

Visual Enhancements

• Alternating left-right layout for dynamic visual rhythm
• Gradient visual placeholders with shimmer animation effects
• Large decorative icons in visual areas
• Directional slide-in animations (fadeInLeft/fadeInRight)
• Staggered timing (0.1s, 0.3s, 0.5s, 0.7s delays)
• Hover effects: icon rotation, scale, and enhanced shadows
• Responsive breakpoints at 768px and 480px

Responsive Design

• Desktop: Side-by-side 2-column grid (50-50 split)
• Mobile: Vertical stack with visual → content ordering
• Tablet: Adaptive sizing with centered text

Design Benefits

The Split Narrative pattern provides:

• Strong Page Rhythm: Alternating creates visual interest and guides the eye

• Individual Feature Focus: Each feature gets dedicated full-width space

• Storytelling Flow: Natural left-right reading pattern

• Animation-Friendly: Perfect for directional slide-in effects

• Modern Editorial Feel: Curated magazine-style layout

This section details on the original issue you should resolve

<issue_title>Redesign "Key Features" Section for Professional Layout and Copy</issue_title>
<issue_description>

The current “Key Features” section looks flat and lacks hierarchy, consistency, and marketing appeal. Each card reads like a technical note rather than a product highlight. To improve credibility and design quality, we need a full structural and copy refresh.

Problems

• No visual or logical hierarchy — all features look equal in importance.
• Inconsistent icon style and poor color balance.
• Copy reads as academic explanations instead of concise product value.
• No single “hero” feature to anchor user attention.

Proposed Solution

Redesign the section with a clear hierarchy and product-driven tone.

Structure

• 1 Hero Feature (centered): Hybrid ML Architecture — highlight the core technology.
• 3 Supporting Features (columns): StyloMetric DNA, Explainable AI, Real-Time Accuracy.

Tone

• Rewrite copy to focus on value and trust rather than internal mechanics.
• Add measurable results and human-readable explanations.

Visual Design

• Unified icon set and typography.
• Light gradient or neutral background to separate from other sections.
• Subtle hover and fade-in animations for interactivity.

Deliverables

• Updated content copy (provided below)
• New layout wireframe or component implementation in Figma/React
• Visual assets (icons + accent colors)

Reference Copy (for implementation)

• Hybrid ML Architecture — Fuses neural networks with linguistic intelligence for real-time, interpretable results.
• StyloMetric DNA — Maps sentence rhythm and lexical depth to identify unique writing patterns.
• Explainable AI — Provides measurable metrics for every prediction, ensuring transparency.
• Real-Time Accuracy — 97%+ verified precision, <100 ms latency, CPU-only runtime.

@copilot 试试改改模式，Split Narrative 模式（左右交错）

适用场景：希望展示技术与应用并重。

每个模块占据一整行，左右交错排版：左图右文 / 右图左文。

效果：

页面节奏感强。

每个特性像一个 mini-section，有自己的气场。

非常适合加轻动画（左右滑入、淡入）。

Implemented the Split Narrative pattern with alternating left-right layout. Each feature now occupies a full-width row with 50-50 content/visual split, creating strong page rhythm and natural storytelling flow.

Changes (commit 3d667bf):

• 4 full-width rows alternating between left content/right visual and right content/left visual
• Directional slide-in animations (fadeInLeft/fadeInRight)
• Gradient visual placeholders with shimmer effects
• Responsive: 2-column on desktop, stacks vertically on mobile
