   GOOD STUFF VENTURES — "The Idea Board"
   -------------------------------------------------------------------------
   Concept: an imagineers' brainstorming whiteboard. Different teammates have
   attacked the board in different marker colors and different handwriting;
   sticky notes are pinned at angles; simple wireframe doodles sketch out
   storylines; annotations (circles, underlines, cross-outs) draw themselves
   in as you scroll, as if someone is marking the board up live.

   Type system (three voices on one board):
     • Caveat        — big marker handwriting (headline energy, quotes)
     • Kalam         — sticky-note / margin handwriting (a second person)
     • IBM Plex Mono — "typed" labels, nav, buttons, folios
     • Fraunces      — editorial headlines (the printed matter pinned up)
     • Newsreader    — long reading copy

   Ink palette (dry-erase primaries):
     board #f4f4f1 · ink #161616 · red #E03E2D · blue #2D6AE3
     green #169E46 · orange #F28A17
   Sticky notes: yellow #FFE259 · pink #FFB7D6 · lime #D8F266
