/* ================================================================
   PARAMIND — TOOL CARDS + SECTION PAGE HEADER (shared)
   ----------------------------------------------------------------
   Tool-card visual pattern lifted from landing.html plus the new
   slim section-page header used on learn.html / practise.html /
   reflect.html.

   USED BY:
     learn.html, practise.html, reflect.html

   NOT USED BY:
     landing.html — keeps its own self-contained inline copy until
                    retired, then this file replaces it.

   REQUIRES (from css/styles.css):
     --color-teal, --color-green, --color-gray-100..800

   NOTES ON ADDED STYLES:
     .card-interview and .card-flashcards glow/gradient/icon
     colours did NOT exist in landing.html. Added here with
     sensible defaults (indigo for interview, teal for flashcards)
     so the cards aren't visually orphaned on the section pages.
     Adjust freely.
