/* Updata microsite — Editorial redesign.
   Every class here is `u-` prefixed. leanscale.css already defines .card,
   .eyebrow, .pill and .note — reusing those names let the brand sheet win
   silently (a lime eyebrow on a near-white pill, and flex:1 on every <p>).
   Namespace everything; inherit the --ls-* tokens and extend them with a
   few local --u-* ones (soft washes, glass, generous radii) that
   leanscale.css doesn't define but this layout needs. */
