/*
 * Story A — chapters 01 (mocks) and 02 (#tests, the module cards).
 * patterns/story-a.php. Port of the first two <section data-ch> blocks inside
 * #how in src/features/landing/landing-page.tsx: every value below is the
 * inline style the TSX drew. The chapter shell (.id-ch, .id-ch__rail,
 * .id-ch__node, .id-ch__body, .id-eyebrow, .id-ch__title, .id-ch__lede) is in
 * base.css.
 *
 * Neither graphic changes with the 900px / 1180px breakpoints: only the shell
 * around them does (base.css).
 *
 * landing.js writes inline: transform + opacity on the graphic (data-gfx),
 * background + transform on each tile (data-tile), opacity + `translate` on
 * each module card (data-mod). Nothing here sets those on those elements
 * except the finished-state tile colours, which inline styles override.
