   KRITEXA LABS — LABS PAGE CSS
   css/pages/labs.css
   Phase 25 — Labs Premium Visual Refinement

   PURPOSE:
     Labs-page-specific styles only.
     All global patterns (.btn-p, .btn-g, .section, .container,
     .grad-text, .sh-eyebrow, .rv, etc.) are NOT redefined here.

   SECTION INDEX:
     1. Labs Hero
        1a. Background grid + node system
        1b. Ambient glow layers
        1c. Hero content (eyebrow, h1, tagline, meta)
     2. Experiments Section
        2a. Status board banner
        2b. Experiment cards (3-column grid)
        2c. Progress bars (purple→cyan gradient)
        2d. ON THE HORIZON sub-section
        2e. Concept / planned cards (4-column grid)
     3. Badge system (shared across Experiments + Builds)
     4. Built & Tested section
        4a. Filter bar (premium pill controls)
        4b. Featured build card (horizontal layout)
        4c. Screen frame placeholder
        4d. Build card grid (coming-soon placeholders)
     5. Products section
     6. Final CTA section
     7. Responsive overrides
     8. Reduced-motion overrides

   SCOPING:
     All selectors prefixed with .labs-* or scoped to Labs-specific
     classes. Does not affect any other page.

   VISUAL DESIGN:
     - Near-black background, deep purple/cyan accents
     - Dark translucent card surfaces: rgba(255,255,255,0.025–0.05)
     - Border: 1px solid rgba(124,58,237,0.18–0.28)
     - Border-radius: 18–24px on cards
     - Hover: translateY(-3px) + border brighter + subtle purple glow
     - Glow on hover only — not continuous
     - Animations: 180–300ms, respects prefers-reduced-motion
