/* ============================================
   EDUARDO GARCÍA PORTFOLIO — HOME
   The three columns of the home page: titles, drawings, dotted reveal
   and details. The section and about pages reuse the column (.hero__column).
   On hover, the drawing turns into its dotted version, in red (on the home
   only: the portrait's dots in «Sobre mí» are black).
   Lines, labels, numbers and buttons have the drawings' mass: solid black
   rules, bold labels, the number as a black block, a solid round button.
