   Amanda Idris — Case Study: "How Aspire Works" (HAW)
   Loads AFTER case-study.css. Reuses the shared shell/sidebar/TOC/
   progress/.cs-ai/.cs-obj/.cs-split/.cs-panel/responsive from
   case-study.css UNCHANGED, and ONLY adds the HAW-specific pieces:
     - .cs-qa       interactive Q&A tabs (Discovery)
     - .cs-quote    indented note/hypothesis blocks
     - .cs-options  "Exploring the direction" option cards
     - .cs-iso      isometric visuals row
     - .cs-struct   page-structure grouped layer panels
     - .cs-showcase stacked final-design mockups (same as Kayn)
   Palette (orange/blue/soft/dark) is inherited from case-study.css.
