/* site-theme.css: default site-level polish over the Theme Studio blocks. Ships with every new full-mode (Theme Studio) site and is registered in config/site.php "site_css". It gives a fresh site a designed look on day one, a soft branded hero band, card depth + a brand top-accent + hover lift, a light-on-dark readable footer, and page rhythm, instead of bare blocks on white. Edit it freely per site, or delete an override you do not want. TOKEN-DRIVEN: every value reads from the Theme Studio --ts-* design tokens (or derives from them via color-mix), so this polish adapts automatically to whatever palette the Theme tab sets. There are no hard-coded brand colors. CASCADE RULE (do NOT remove the `body.ts-page` prefix): the engine emits site_css BEFORE the per-block
