/* Shared look for the Card Asylum web admin.
 * Every admin page links this before its own <style>; page-specific rules
 * (calendar, sparklines, bin grid, status badges…) stay in the page and
 * override these. Brand colours follow the storefront (deep green + cream +
 * gold); page bodies stay light/neutral so dense tables are easy to scan.
 * Light/dark follows the system setting. */
