/* Clasa home.
 *
 * One claim: school messaging where the teacher's phone number is never in the
 * room. Everything here states that claim, proves it, or asks for the download.
 *
 * COLOUR — the fix
 * The first pass carried five: green, a green wash, a red for the "bad"
 * column, black and grey. Five colours on a page with one idea is not a
 * palette, it is noise — and the red did the argument active harm. A product
 * that has to paint its rival red is not a product that is confident.
 *
 * The correction after that was an overcorrection: green got demoted to a
 * four-letter label and the one button on the page became a solid black brick
 * with no brand on it anywhere. A messenger whose accent is #01DA51 should not
 * ask for the download in black.
 *
 * So the rule is about ROLE, not quantity. Green means "this is the action, or
 * this is the number that matters": the button, the struck-out rival, the zero,
 * the tap. Ink is type, grey is support, and nothing else gets a colour — the
 * contrast column is still weight and opacity, never red.
 *
 * TYPE, AND NO PICTURE
 * The mockup is gone. It was a stock phone standing in for an argument, and it
 * made the hero fight itself for attention. With no illustration the sentence
 * has to carry the page — which is the right pressure to be under, because the
 * sentence is the product.
 *
 * MOTION — and why there is no library
 * The reference (cofee.life) runs GSAP + ScrollTrigger + Lenis + Swiper. Lenis
 * is the part that feels expensive, and it earns that by replacing native
 * scrolling with a JavaScript loop: ~100KB of vendor to make a page about being
 * the calm option stutter on the cheap Android phones this audience holds.
 * Reveals are IntersectionObserver, the pinned card is position:sticky, the
 * rest are CSS transitions.
