/* /sdlc hero stage — the SDLC agents at work on a pixel pipeline board.
   Authored at 1600×480 (world px), scaled to fit by sdlc/hero.js; phones get a panning camera.
   Only transform/opacity animate on the timeline; chips, bubbles, tags, ticker and meter are set from timeline time.
   Sprites are <img> rendered pixelated at 6×. Fonts (Press Start 2P, VT323) come from the page's Google Fonts <link>. */
