/*
  Clark & Enersen tools site styles.
  Palette and type follow the Clark & Enersen Digital Brand and Interface Guide.
  Spacing, radii, and layout are proposed digital patterns from that guide, not adopted firm policy.

  FONT DELIVERY (open item before firm-wide launch):
  The local preview loads /assets/fonts/acumin-variable.otf, which is gitignored and never pushed.
  For the deployed site, use the firm's Adobe Fonts Web Project. Paste its CSS link here, for example:
    @import url("https://use.typekit.net/XXXXXXX.css");
  Adobe serves the family as "acumin-pro" and "acumin-pro-semi-condensed", which are already in the stacks below.
