/* ============================================================================
   GROUP PRESENTATION — SHARED STYLESHEET
   "CEO Narcissism, Overconfidence, and Gender Diversity"
   Universitas Internasional Batam

   PURPOSE
   A single stylesheet for a 6-person presentation. Every presenter applies the
   SAME class names below, so all six sections render with one consistent look.
   There is no per-person styling. The only thing that differs between slides
   is the section number and the presenter's name in the header.

   SECTION -> PRESENTER MAP
     01  Opening & Context           -> Presenter 1
     02  Theory & Hypotheses         -> Presenter 2
     03  Methodology                 -> Presenter 3
     04  Descriptive Results         -> Presenter 4
     05  Direct Effects (H1-H4)      -> Presenter 5
     06  Moderation, Robustness &
         Conclusion (H5-H8)          -> Presenter 6

   HOW TO USE (each presenter)
   - One <section class="slide"> per presentation page.
   - Copy the <header class="slide__header"> pattern exactly; change only the
     section number and the presenter name.
   - For every data table use: <table class="data">.
   - For every hypothesis use: <span class="hypo hypo--supported">H1</span>
     (states: --supported / --rejected / --neutral).
   - For the headline findings use: <div class="callout"> with the matching
     modifier class. Do not invent new colors here.

   SEMANTIC COLOR CODE (kept identical across all sections)
     green   #2f6e4e  = hypothesis supported / positive effect
     crimson #b3232a  = hypothesis rejected  / negative effect
     amber   #b58a2e  = null / non-significant / caution
     ink     #14213d  = primary text & structure
