### Page Motion (opt-in)
Add `motion: true` to a page's front matter to load `src/js/motion.js`. On `page.njk` and `markdown.njk` layouts this fades in the page header and reveals top-level content sections (card grids stagger card by card) as they scroll into view. Pages on `base.njk` can mark elements directly with `data-reveal`, `data-reveal-group`, or `data-reveal-auto`. All motion is skipped for `prefers-reduced-motion`, and content stays visible without JS. The topographic background (`src/sass/_topo.scss`, `src/js/topo.js`) applies sitewide; regenerate its SVG with `node scripts/generate-topo.js [seed]`.
+### Trail Progress (opt-in)
+Pages on `base.njk` add a `camps` list to front matter to show the trail progress system: camp ticks (real anchor links), a pinned rail hiker on wide screens, and a progress track plus tick bar on small screens. Each `id` must match a section on the page, and the first camp is the trailhead.
+
+```yaml
+camps:
+ - { id: top, label: Trailhead }
+ - { id: work, label: Work }
+```
+
+`src/_includes/trail-progress.njk` renders the markup, `src/js/trail.js` moves the hiker and marks the active camp (it keeps running under `prefers-reduced-motion`, stepping between camps), and `src/sass/_trail.scss` holds the styles. The home page also reads `meta.email`; the "Email me" button stays hidden until it is set.

### Modify Site Navigation
Edit `eleventyNavigation` in page front matter:
- `key`: Unique identifier
