/*
 * Luma Clinic: a full page for a private oral and facial surgery practice.
 *
 * Nearly monochrome. Anthracite, white and one very light grey carry the whole
 * page; the only colour is the gold of the review stars and the four Google
 * tones in its mark. Sections separate by a change of surface, white against
 * near-white, never by a rule.
 *
 * Two motifs run through it. Photographs sit in generously rounded frames and
 * grow very slowly under the cursor, and every block arrives once with a short
 * lift. Everything else stays still.
 *
 * House rules: no shadows, no coloured overlays on the photographs, buttons
 * with a small radius rather than fully round ones.

            <p>
              Beauty is never the goal for me, it is the result of a careful procedure. I take my
              time, I listen, and together with every patient I develop a plan that suits their face
              and their story.
            </p>
            <p>
              With more than 15 years in implantology, oral surgery and aesthetic facial surgery, I
              combine medical precision with a fine sense for natural results.
