/* Stretcher (web) — styles.

   Colour scheme taken from the Frizzy G logo: mid-grey ground, neon lime,
   and black for every outline and hard offset shadow. One scheme, no themes.

   Contrast rules the palette forces:
     lime on grey is only ~3:1, so lime text always gets a black outline (the
     logo treatment, .logo-text) or sits on black;
     body text is black on grey (5.3:1) or black on lime (15:1);
     on black panels, text is white or lime (both well over 12:1). */
