   Oolong Tea Home — design system v2
   ----------------------------------------------------------------------------
   Direction: specialty-tea editorial. Think a printed tea journal, not a blog.
   - Type: Fraunces (display, optical-size axis) + Newsreader (text serif).
     No system-sans anywhere in reading surfaces.
   - Colour: deep pine ink on warm paper; aged brass as the single accent.
   - Layout: asymmetric editorial grid, generous margins, real hierarchy.
   - Motion: short, ease-out, never bouncy.

  /* --- the grid -----------------------------------------------------------
     Two right edges only. Reading measured the whole design: with six
     different box widths (1200 / 1104 / 826 / 806 / 791 / 688) the page had
     no vertical line to hold it together and every figure looked like it was
     escaping the column.
       --measure      reading column. Prose measure ~66 characters.
       --col-figure   the breakout. Figures, tables and pull quotes are
                      ALLOWED past the text column - that is what a printed
                      feature does - but by a controlled 30%, not by 74%.
     Band elements (hero, banner, related, jump grid) stay full width on
     purpose: they are section openers and closers, not reading content.

     These MUST be rem, not em. max-width in em resolves against the
     ELEMENT's own font-size, so an "em" column silently means something
     different on a 24px pull quote than on 17px body text - which is how
     six different widths got shipped in the first place. */
