   ENFILADE CAPITAL — DESIGN SYSTEM v2
   Monochrome research-house. Editorial. Strict contrast.
   --------------------------------------------------------------------------
   Architecture
     1. Tokens (raw values)               — palette, type, space, motion
     2. Surface system (the key idea)     — wrap any block in .surface-*
                                            child components auto-adapt via
                                            cascading custom properties
     3. Reset + base typography
     4. Layout primitives                 — container, section, grid
     5. Typography utilities              — display / eyebrow / label / body
     6. Rules + dividers
     7. Components                        — card variants, ledger row, kpi,
                                            button, form, nav, hero,
                                            section-index, dateline, tag
     8. Footer
     9. Reveal-on-scroll animation
    10. Responsive
   --------------------------------------------------------------------------
   Pages link one file: <link rel="stylesheet" href="css/enfilade.css">
   Adding a new page = composing classes, never writing new CSS.

   --------------------------------------------------------------------------
   Chapter-boundary approach used by Bloomberg Businessweek (Pentagram),
   the Financial Times and The New Yorker: colour changes are *marked*, not
   *dissolved*.  A 2 px black rule sits at the top of every non-paper
   section — it is the chapter break.  No gradients, no mid-tone mud.

   The rule is drawn on a container that spans the FULL viewport width so it
   reads as a printed folio line, not as a section-head divider.
