   Revive Watch — Brand Stylesheet
   Visual direction: "Ice-age field notes" — prehistoric / amber-frost.
   The species are coming back; the board reads like a frost-dusted
   naturalist's ledger: warm cream paper, glacial teal ink,
   warm amber "life returns" sparks, dark ink text.

   Palette (ui-design-spec §3, app brief §13):
   --cream        #FDF6EC   page background (warm cream paper)
   --cream-deep   #F0D8C0   deeper cream surfaces (sand/amber family)
   --cream-card   #FFFDF6   elevated card surfaces
   --teal         #00897B   glacial teal primary (primary actions, links)
   --teal-dark    #00695C   deep glacial teal (hover, AA text)
   --teal-soft    #E4F1EE   teal tint surfaces / chip backgrounds
   --amber        #B26A00   warm amber accent (sparks, highlights)
   --amber-deep   #8A5200   deep amber (AA text on cream)
   --amber-soft   #F6E7CF   amber tint surfaces
   --ink          #1B1C18   dark ink (headings / primary text)
   --ink-muted    #5C5D52   muted body text (AA on cream)
   --ink-faint    #8A8B7E   captions / meta text
   --border       rgba(27, 28, 24, 0.12)

   Typography:
   Display: "Fraunces" (warm, editorial, prehistoric-museum character)
   Body:    "DM Sans" (refined, readable)
