/* =========================================================================
   Tool Wall — light, papery, exhibition feel
   --------------------------------------------------------------------------
   The "show-and-tell" face of the session. Cream paper, generous whitespace,
   Georgia headlines, cards as pinned Polaroid-ish notes with subtle
   rotations and a small green pin in the top-right of each.
   --------------------------------------------------------------------------
   Colour: CQU primary (Dark Green / Hero Green) anchors. Tertiary colours
           used as category tints so the wall scans visually. Body on cream.
