/* Dr Sudha Vasanth, Vasanth Clinic, KGF.
 *
 * The one strong fact she owns: MD in Internal Medicine. In KGF most of the
 * high street is MBBS or BAMS, so an MD physician is a different thing
 * entirely — and a patient has no way of knowing that. So the page does not
 * display the letters, it EXPLAINS them. That is the signature, and it is the
 * only genuinely useful thing this page can do for someone deciding.
 *
 * Split screen: left fixed with her name, the letters and the call, because
 * call-or-don't is the only decision here and it must never scroll away.
 * On a phone the left becomes a card at the top and the call becomes a
 * sticky bar, which is the honest version of the same idea.
 *
 * Slate blue-grey rather than clinical blue-and-white, which would make her
 * look like every other clinic page. One coral, used only on the call, so
 * the eye has exactly one place to land.
 *
 * No photographs. Her Instagram is medical comedy featuring colleagues and
 * juniors; other people's faces do not belong on her clinic page.
