   Splash screen — the landing page (index.html)
   --------------------------------------------------------------------------
   Composition is authored against the 1920x1000 Figma frame:

     splash-bg.jpg      full-bleed watercolour landscape
     copy               centred, first line ~32.5% down the frame
     splash-envelop.jpg 911x474 -> 47.45% of frame width, bottom-anchored

   --stage is the width of that 1920x1000 frame scaled to COVER the viewport,
   which is the same box `background-size: cover` paints into. Positioning
   everything as a fraction of --stage therefore keeps the copy and the
   envelope locked to the artwork behind them at any window size. The 190vw
   ceiling is the portrait escape hatch: without it the envelope would be
   wider than a phone screen.

   The three envelope frames are JPEGs on a white ground, so they are
   composited with mix-blend-mode: multiply — white drops to the backdrop
   while the navy paper, cream card and ivory wax seal all survive. A
   chroma-key would have punched holes straight through the seal and card.
