Two-column portfolio index built as a plain, fully editable Etch tree: section > container > header (eyebrow, h2, "View All Projects" link with an arrow icon) > a grid of four "Project Card" component instances (image, alt, title, category, url), each a fully-clickable card (stretched link) with an image that zooms on hover/focus and an arrow that slides in. Section option is data-theme (light|dark) on the section. Cards rise in on scroll via @starting-style (no @keyframes), skipping the motion under prefers-reduced-motion. Container queries take the grid from one column to two.
