 *  - 2019 Brand Style Guide (research/brand_styleguide_text.txt)
 *  - Live www.sprinklr.com extraction (research/site_extract.json)
 *
 * Brand says: human, authentic, joyful. Sentence case. Color used purposefully.
 * Body copy stays Steel Gray or black.
 *
 * Primary type face is Proxima Nova (commercial, paid). Mulish is the closest
 * free Google Fonts substitute and is used here as a fallback. SUBSTITUTION
 * FLAGGED — replace @font-face with licensed Proxima Nova for production.
