/* PICPAC 3PL FUNNEL: SHARED STYLESHEET
   Restyled 2026-09-21 to the "stoic." design reference (see
   ../design-reference/STOIC-Design-Brief.md): near-black ink, light gray
   ground, no brand accent color, solid black pill buttons, one all-black
   rounded calculator section, monoline icon badges, huge whitespace.
   Light tokens on :root, dark overrides under prefers-color-scheme (guarded
   by :not([data-theme="light"])) AND under :root[data-theme="dark"] so an
   explicit toggle would win in both directions even though no toggle exists
   yet. Element IDs referenced by calc.js / inline page scripts are
   untouched; only classes/markup around them changed. */
