/* ===== RESEARCH_BADGE_V1: research status badge (Selection / In progress / Concluded / Soon) =====
   Markup: templates/research_badge.html. Used in block_blog_cat.html (cards), blog.html (list), blog_post.html (article).
   Design 2026-10-19:
   - badge: cyan text, thick cyan bar on the left that is taller than the text; in cards the bar is flush
     with the card's left edge and the text + the date below are indented;
   - tooltip: purple box over the badge + date, as wide as the card, generous padding, curved tail at the top-left.
   Shown on hover / keyboard focus / tap. */
