First slice of the per-module CSS strategy: introduce
shared/css/tokens.css as the always-present, theme-agnostic base token
layer, loaded before all other stylesheets.
- Defines --font-mono (ui-monospace stack). Several feature sheets used
var(--font-mono, monospace) with no definition, falling back to bare
monospace; this unifies them with the richer stack used elsewhere.
- Hoists the --page-* identity hues out of css/admin.css so they belong
to the base layer rather than the admin stylesheet. Values unchanged.
