/* =============================================================================
   MAD BREWS — FERMENT
   -----------------------------------------------------------------------------
   Warm paper, forest green, copper. Fraunces for voice, Inter for everything
   that has to be read quickly. Rounded cards and pills, flat surfaces, no
   shadows. Light and dark themes from the same token set.

   What stays from the lab-notebook version is the part that was never
   decoration: every number is a reading, curves go only through readings that
   were taken, and the graduated rail still runs down the left edge.

   THE RULES THIS FILE KEEPS
     1  TOKENS ONLY. Every colour is an HSL triplet below, so the light theme,
        the dark theme and the inverted bands are one palette, not three.
        Small text uses --accent-text (AA on its ground); --accent is for
        fills, marks and large type.
     2  ONE ACCENT WORD per h1/h2 — the <em>. It is copper, not italic.
     3  NO SHADOWS. Depth is a 1px border and a change of surface.
     4  EVERY NUMBER IS A READING: tabular figures, slashed zero, unit in .u.
     5  ONLY THE RAIL FOLLOWS THE SCROLL. Reveals fire once and travel 12px.
