/* PT Coba Dulu Siapa Tahu: corporate site. Brand Identity v1.1.
   Sage and Spark are fills only, never text. One Spark per page (it lives in the logo mark).

   Layout system (one grid for every block):
   - Container: content max 1072px, side padding 20px (<760) and 32px (>=760).
   - 12 columns, 24px gutter. From 960px three-up blocks span 4 columns each and
     two-column blocks split 7 + 5; below 960px every block stacks on the full width.
     Running text is capped at 7 columns (and 40em) so line length stays readable.
   - Vertical scale: 4 8 12 16 24 32 48 64 96 (--s1 to --s9). */
