   Story Based Hub — "Printed Matter" Design System

   Concept : The Typographer's Workshop — editorial, literary studio
   Fonts   : Fraunces (quirky optical-size serif) + Outfit (geometric)
   Palette :
     --primary:   #D94A38  rust red         ← accents, CTA, chapter marks
     --secondary: #2A363B  dark charcoal    ← header icon, footer bg
     --accent:    #99B898  sage green       ← tags, badges, highlights
     --bg:        #FDFBF7  warm off-white   ← page background
     --text:      #2C2C2C  near-black       ← body text

   Unique Feature : CSS auto-counter "chapter marks" on .article-body h2
                    — every H2 shows its chapter number as a small
                      rust-red label, giving a literary book-chapter feel.
                    + blinking cursor on hero H1 (pure CSS keyframe)
                    + thin rust-red reading-progress bar on article pages
