/* ==========================================================================
   THEME — "the-bonding-space"
   --------------------------------------------------------------------------
   Studio-editorial paint layer for a literary magazine on adult intimacy,
   chosen family, and the small rituals that hold connection together.

   Palette (4 brand HEX, used twice — once per scheme):
     #FAFAF7  Studio White   — light page background
     #1B1C2A  Midnight Ink   — body text / dark page background
     #B05E9E  Orchid Plum    — primary accent (links, kickers, rules)
     #3DBFA3  Sage Teal      — secondary accent (hairlines, hero, surface highlights)

   Structure (grid/flex/spacing) is owned by layout.css ("journal"). This file
   only paints colors + fonts + accent flourishes on top. No layout written.
