/*
 * base.css
 * -----------------------------------------------------------------------
 * Original, self-authored base layout & component stylesheet for the
 * Steven W. Charchut DMD, MS Orthodontics website.
 *
 * This file replaces the third-party "Sesame Communications" global
 * framework stylesheet that this site previously loaded from
 * srwd.sesamehub.com. It contains no Sesame code and was written from
 * scratch by inspecting only this repository's own markup
 * (index.html, meet-dr-steven-charchut.html, treatment-options.html,
 * appointment-request.html, office-tour.html, testimonials.html, etc.)
 * and the site-specific override stylesheet assets/css/local.css, which
 * loads immediately after this file and supplies the brand-specific
 * colors, spacing and fine positioning on top of the structure below.
 *
 * Brand palette (see assets/css/local.css and the inline logo SVG):
 *   teal  #29605a   gold/tan #beb87e   navy #141b52
 * Brand fonts (already hosted locally, @font-face in local.css):
 *   'Lato' (body), 'Vujahday Script' (decorative script accents)
