/*
 * pawandi.com — Paw & I. The NoteMem site style (notemem-style skill): warm paper white and near-black ink,
 * black buttons, soft pastels (peach, lilac, butter, sky, mint) for tiles and the haze behind the hero. The one
 * accent is terracotta instead of NoteMem's blue, warmer for a pet brand; white on it passes 4.5:1. The header
 * and the phone's bottom button float on a progressive blur (eight backdrop-filter layers, 0.5px → 64px,
 * MengTo/Skills web-design/progressive-blur). One moment of motion: the photos, the framed proof and its
 * approve button arrive as the page opens.
