/* ============================================================
   GRAMMAR CHECKER TOOLS — Design System
   Concept: "The Editor's Desk" — a proofreader's red pen on paper.
   Palette:
     --paper:      #FAF8F4  (warm paper background)
     --ink:        #1E2430  (deep ink navy — near-black, not pure black)
     --ink-soft:   #4A5264  (secondary text)
     --correction: #C4432E  (proofreader's red — errors, accents, CTAs)
     --confirmed:  #2F6D5C  (editor's green check — correct/success)
     --rule:       #E4DFD4  (hairline paper rule)
     --card:       #FFFFFF
   Type:
     Display/headings: Georgia/serif stack (manuscript feel)
     Body/UI: system sans (legibility on a tool-heavy site)
   Signature: the red "squiggly underline" motif from real spellcheckers,
   used as a literal decorative underline on key headings.
