/* slide-shell.css — the ONE shared stylesheet for both deck.html and index.html.
   They must look pixel-identical (see CLAUDE.md), so this is the only place slide visuals
   are defined. Edit here, never duplicate a rule back into either HTML file's <style>.
   deck.html-only elements (notes-panel, timer-badge) and index.html-only elements
   (follow-bar) are both included here — an unused rule in one page is harmless. */
