/**
 * hood.css — chapter 06, "Under the hood" (js/hood.js).
 *
 * A 12-column bento in the site's own language: every tile opens with an
 * icon tile + title + lead (as the planner's cards do); Integration is the
 * dark "pass" material; Data integrity uses the planner's gliding
 * gradient highlight; the signing dialog has the batch stepper's numbered
 * dots; Security closes the grid full-width, so no row is left ragged.
 * Loops animate transform / opacity (the flow lines excepted: a small SVG),
 * and base.css pauses them while the chapter is off screen.
