   Proportions measured from nikiforovanina.github.io (1024px viewport):
     columns  48px gutter; 290px photo column | 90px gap | 577px text column
     photo    290 x 387 (3:4), square corners
     body     18.4px, light weight, #1a1a1a
     name     40px / 700, sits BELOW the photo
     headings 25.6px / 500, in the text column (no left rail, no dividers)
     links    same colour as the text, underlined — no blue anywhere
   No header bar, no nav, no JavaScript. */
