/* SmartReminder - design tokens, reset and typography.
   Light is the base palette; dark is redefined both by system preference and
   by an explicit [data-theme] stamp so a Telegram/user override always wins.

   The palette is deliberately neutral - warm paper in light, graphite in dark -
   so the only saturated colour on a screen is a payment's status. That keeps
   "red means overdue" legible instead of competing with the interface. */
