/* The client portal's design system.
 *
 * Hand-written, and a single file, because the console it belongs to has no build step:
 * templates are Jinja, behaviour is HTMX, and a strict CSP drops anything inline. None of
 * that is what made the old screens look unfinished — that was a hundred lines of ad-hoc
 * CSS with no scale, no rhythm and no states. This is the scale.
 *
 * Read in four parts: tokens, then the shell, then components, then motion. Nothing here
 * is scoped to a page; a screen is assembled out of these and gets its polish for free.
