README

The site of a survey office for moving ground, made with the admin's own blocks, design tokens and the design's scripts: a WebGL field of contour lines behind every page that follows the pointer, the scroll and the page, sections pinned to the scroll, a surveys index you filter, and a field that keeps drawing across pages that change without a reload. It works without scripts, with less motion and on a phone, in English, Dutch and French.

Install

composer require letterncms/fathomline
php cms kit:apply fathomline --dry-run
php cms kit:apply fathomline

Or choose Fathomline when you install (php cms install --kit=fathomline, or in the browser), or under Design → Site Kits.

What it brings

• Pages in a tree: Home, Surveys, Office with Method and Corrections, Journal, Commission and Privacy, each in English, Dutch and French.
• Surveys, six of them, with a plate, a summary, the place and the numbers that steer the field behind their page.
• Journal with a second kind of entry, the Field Report (station, instrument, conditions, a gust that shows only for a breeze or a gale, a calibration date once calibrated); one note scheduled, one with an end date and one still a draft.
• Topics, a taxonomy with an archive page per topic.
• Globals for the footer and the site's labels, a main menu with a submenu and a footer menu.
• The design: tokens for light and dark, templates and components, Hanken Grotesk, EB Garamond Italic and IBM Plex Mono, the scripts (field, plate, cue, rows, gauge, smooth) with three.js and Lenis vendored, and the plates, photos, a PDF and a 3D model they show.

Needs

Lettern 0.28 or later. No plugins: the Journal's notices and the Commission page ask people to write to the office; with Forms or Brevo on, a form or a signup block goes in their place. Applying it brings scripts, so it needs the Edit Custom CSS and JavaScript permission. The fonts and libraries keep their own licences: see NOTICE.md.
