/* ==========================================================================
   MAIN STYLESHEET — SECTION-SPECIFIC STYLING ONLY
   This file styles the nine portfolio sections (hero, about, work, services,
   process, clients, testimonials, contact) and nothing else.

   All global styles (reset, base, typography, buttons, placeholder art, reveal contract) are in:
   - styles/tokens.css (design tokens)
   - styles/base.css (reset, typography, buttons, placeholder art, reveal contract)
   - styles/layout.css (container, section rhythm, header, footer)
   - styles/interactive.css (lightbox + SR status region — owned by t2)

   Do not redefine any shared class (.container, .section-head, .btn, .eyebrow,
   .placeholder, .dark-section, .reveal etc.).

   Section hooks used here: #hero/.hero, #about/.about, #contact/.contact —
   both the id and the class are emitted in index.html.
