   CASASOL — STYLES v3.5
   ──────────────────────────────────────────────────────────────────────
   Modular CSS organized into sections that mirror the HTML structure.
   Each major block is marked with a heavy banner; subsections with rules.

   Sections (search for the banner to jump):
     [TOKENS]      — design tokens / CSS custom properties
     [RESET]       — reset, base, body, paper grain
     [TOPBAR]      — top navigation
     [HERO]        — hero section
     [SECTION]     — shared section scaffolding
     [THESIS]      — §I — The Asymmetry
     [POSTCARD]    — the B200 postcard (in §I)
     [SIDENOTE]    — secondary callouts (Hobbesian in §I)
     [CANDOR]      — §II — The Real Constraint
     [ENGINE]      — §III — diagram frame + tier descriptions
     [PAIR]        — §IV — terminal + reply
     [COMPLIANCE]  — §V — comp grid + Article 22
     [AUDIENCES]   — §VI — 2x2 audience grid
     [SUBSTRATE]   — §VII — dark substrate section
     [EVENT]       — §VIII — event card + email row
     [FOOTER]      — footer
     [MOTION]      — entrance animations
