/*
 * Hand-written CSS, no build step. Propshaft serves every file in this folder
 * through `stylesheet_link_tag :app`, in alphabetical order:
 *
 *   tokens.css      design tokens (colors, spacing, type) on :root
 *   base.css        element defaults
 *   layout.css      page shell: header, main, footer, page header
 *   components.css  reusable pieces: buttons, cards, forms, tables, flash, badges
 *
 * Rules use tokens only: no raw colors or sizes outside tokens.css.
