The head script reads livewire-material.theme.contrast (standard, medium, high or
system, kept under its own storage key), asks the operating system while the choice
is system and follows it, and writes <html data-contrast> — nothing for standard,
which is what the stylesheet's plain blocks already are. It writes
<html data-motion="standard"> for motion.scheme, and both attributes, with the new
choice and key ones, survive wire:navigate. $store.theme gains contrast,
resolvedContrast and setContrast(); the theme-color meta takes its surface from the
resolved level. Plan: docs/plans/material-3-alignment.md, steps 5 and 7 (core C2, C9).
