/* ============================================================================
   HARLEY’S — DECK.CSS  ·  A+ coffee-table 16:9 edition
   The `bb-` slide layer. Slide authors consume ONLY these classes + theme tokens.

   This is the gallery-grade deck contract. Like B&O (luminance pacing) and F1
   (rationed red interruption), it paces dramatic full-bleed DARK breathers
   against clean LIGHT proof spreads. The deck IS the proof of the system:
   every slide obeys the canon it expresses.

   LOAD ORDER (matters — fonts → theme tokens → deck layer):
     <link rel="stylesheet" href="./assets/fonts.generated.css" />
     <link rel="stylesheet" href="./assets/tokens.css" />     (@imports tokens.generated.css)
     <link rel="stylesheet" href="./assets/deck.css" />       (THIS FILE)

   GOVERNING LAW (harleys CANON.md — Oak Room):
   - SHARP corners (radius-none is CANON, not preference). FLAT (every shadow
     resolves to none — CANON). NO celebratory motion; the pages are
     photographs at rest.
   - ONE family: EB Garamond (--font-display AND --font-body). Source Sans 3
     exists ONLY as an operator-amendment utility register (what is USED, not
     READ) — never a display or body face. Tabular figures on all countables.
   - Lamplight amber (--accent) is QUARANTINED: medallion ring, section rules,
     highlight washes behind countables. NEVER interactive, NEVER a filled
     affordance, NEVER >~10% of a surface. See §7 AMBER.
   - IDENTITY = the RING MEDALLION (serif H inside a double ring — never the
     bare H) + the HARLEY’S WORDMARK (wght 500, tracked +80) + STACKED LOCKUP.
     Real SVG marks are PLACED (mask-tinted), never typeset — except the single
     wordmark-anatomy teaching slide. See §5.
   - WCAG 2.2 AA floor; focus = ring ALWAYS paired with a weight/underline/
     position change; color never the sole carrier; DOM order = person →
     dated fact → place → telephone (P-L-195).
   - Imagery register = THE COMPOSED FINISHED ROOM (oak, drape, the long rail,
     lamplight) + the East Texas land — via .bb-slide--veil plates and
     .bb-slide--doc-figure mounts. No aura photographs, no dated-label
     workroom voice, no posted-record scale.
   - There is NO button and NO primary CTA in this system: Button is
     substituted by the ProofEnclosure (§H2). Never button-treat the phone.

   This file DOES NOT redefine theme tokens. It CONSUMES var(--bg-canvas),
   var(--fg-primary), var(--accent), var(--on-accent), var(--font-display) etc.,
   and only defines --bb-* deck-layout primitives. A handful of explicit STEEL
   tones reference REAL primitive ramp tokens (--harleys-oak-room-primary-800 etc.)
   from tokens.generated.css — those are sanctioned, not invented.
