yoge 409bbf742e feat: optimize docs pages and add 4 new doc articles (en + zh)

- Rewrote DocsListPage and DocDetailPage with landing.css aesthetic
  (icon cards, skeleton loader, prose styles, CTA box)
- Added docs-specific CSS to landing.css
- Created image-to-latex, copy-to-word, ocr-accuracy, pdf-extraction
  articles in both English and Chinese
- Updated DocsSeoSection guide cards to link to real doc slugs

Image to LaTeX

TexPixel's core feature is converting formula images — from photos, scans, or screenshots — directly into LaTeX code you can paste anywhere.

How It Works

Upload your image — Drag and drop a JPG or PNG into the upload zone, or click to browse. You can also paste from your clipboard.
AI processes it — Our model detects the formula region, runs OCR, and generates structured LaTeX in under a second.
Copy the result — Click the copy button next to the LaTeX output. Paste directly into Overleaf, VS Code, Word, or any LaTeX editor.

Input Requirements

Requirement	Details
File formats	JPG, PNG
Max file size	10 MB
Recommended DPI	150 DPI or higher
Background	White or light backgrounds work best

What Gets Recognized

TexPixel handles a wide range of mathematical content:

Algebra — equations, inequalities, polynomials
Calculus — derivatives, integrals, limits
Matrices — 2×2 up to large arrays
Greek letters — α, β, γ, Σ, Π, and more
Subscripts and superscripts — x_i^2, a_{n+1}
Fractions — \frac{a}{b}, nested fractions
Square roots and radicals — \sqrt{x}, \sqrt[n]{x}

Example

Uploading an image of the quadratic formula gives you:

x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}

An image of an integral:

\int_0^\infty e^{-x^2}\, dx = \frac{\sqrt{\pi}}{2}

Tips for Best Results

Use clear images — avoid blur, shadows, or low contrast
Crop tightly — the less background, the better the focus
Dark ink on white paper — ideal for handwritten formulas
Avoid rotated images — keep the formula horizontal
One formula per image — for complex multi-part work, crop each formula separately

Limitations

Extremely faint or pencil-written formulas may have lower accuracy
Hand-drawn arrows or annotation marks outside the formula may be ignored
Very large matrices (10×10+) may have reduced accuracy

Copy Options

After recognition, you can copy output in multiple formats:

LaTeX — raw LaTeX string
MathML — for web embedding
Markdown — $...$ inline or $$...$$ block
Plain text — Unicode approximation
