   TRU72 — OREGON ALIAS SHEET  (the D39 re-skin)
   --------------------------------------------------------------------------
   Oregon's green-and-rust palette is RETIRED (D39). Oregon keeps its own token
   NAMES — --green, --cream, --rust, --tan — because 106 pages and thousands of
   declarations reference them, but every name now resolves to the approved six
   in tru72-tokens.css. Same system as North Carolina, same values, one place to
   change them.

       RETIRED                      APPROVED FIVE (D42)
       --green      2C4A2E   ->    INK            #3D3F3F
       --green-deep 1F3621   ->    INK            #3D3F3F
       --green-ink  243D26   ->    SCENERY GREEN  #696859
       --cream      F5EFE0   ->    PAPER          #FFF6DC
       --rust       B6581E   ->    SCENERY GREEN  #696859
       --rust-deep  A24017   ->    INK            #3D3F3F
       --tan        D4A958   ->    LINEN          #CBC0AA
       --rule       D8CCB0   ->    LINEN          #CBC0AA

   WHY --rust BECOMES SCENERY GREEN, NOT A GOLD
   Oregon spends --rust on small type: eyebrows, active nav, list bullets, the
   accent word in a headline. On PAPER, ANTIQUE GOLD is 2.4:1 — it fails. SCENERY GREEN is 5.2:1 and is in the palette. The gold
   stays where the brand guide puts it: rules, keylines and borders, which is
   what --rust-rule below is for.

   WHY --tan BECOMES LINEN, NOT ANTIQUE GOLD
   Oregon spends --tan on small type sitting on a dark band. ANTIQUE GOLD is
   4.0:1 on INK — cleared for display type at 24px+, not for an 11px eyebrow.
   LINEN is 5.7:1 on INK. --tan-metal carries the gold for the 24px+ and
   decorative cases.
