   RUBIN — beetroot kvass concentrate · A–Zh production site
   --------------------------------------------------------------------------
   DESIGN SYSTEM (read me first)

   Palette (exact, all via custom properties below)
     ruby-950  #22050F  near-black ink (stage sections, footer)
     ruby-900  #45091F  default dark page ground
     ruby-800  #5B0F2E  deep beetroot
     ruby-600  #8E1B45  beetroot (primary brand ink on paper)
     ruby-400  #C23A6B  bright ruby (accents on dark grounds)
     bone      #F4ECE1  warm bone / cream paper
     bone-2    #EADFCF  shaded paper
     forest    #2F5D3A  mint-leaf forest green (text-safe on bone)
     mint      #93C9A0  mint highlight (text-safe on ruby)
     citrus    #FF7A1A  hot citrus — sparingly; on bone use #B5470A for text
     turmeric  #E2A12A  illustration only
     ink       #1F0A12  near-black text on paper

   Surfaces — every chapter declares data-surface:
     base     = page ground (ruby dark in dark theme, bone in light theme)
     contrast = the opposite (bone paper in dark theme, ruby in light theme)
     stage    = always near-black ink, used for "product render" moments
   Each surface re-declares --bg/--fg/--muted/--line/--accent/--green/--ruby,
   so components never hard-code colours.

   Type
     Display: Fraunces (variable: opsz, SOFT, WONK) — high-contrast, a little odd
     Text:    Instrument Sans — clean grotesk for reading
     Data:    DM Mono — quantities, batch numbers, lab-log feel
     Scale is fluid (clamp). Hero runs to ~15rem; body 1.0625rem / 1.6.

   Space
     4px base. --sp-1..--sp-9 = 4 8 12 16 24 32 48 72 120.
     Chapters breathe (≥ 120px vertical on desktop), then go dense inside
     ledgers, tables and calculators.

   Motion
     One easing family: --ease-out (expo-ish) for reveals, --ease-spring for
     magnetic / UI. Things enter by rising 24px + unmasking; SVG strokes draw;
     numbers count. Everything idles when off-screen and collapses to instant
     under prefers-reduced-motion.

   Shapes
     Radii are mostly 0 or pill (999px); no uniform soft-shadow cards.
     Edges are drawn with hairlines (--line) and offset "print" shadows.
