   Client feedback 15.09 (voice message): text sat overlaid directly on the

   текст непонятен из-за картинки... разделить их как бы хочется". Split into
   two panels (text | photo) at the time.
   Client feedback 16.09 (voice message, reversed the above): "оставим
   прежний вариант, когда текст на картинке — эта маленькая картинка вообще
   убого смотрится... картинку поярче, а текст менее заметным". Back to a
   single combined hero — but this time the photo stays full-bleed and BRIGHT
   (no overlay for most of its area), and the text sits over a narrow
   left-side gradient only, small and light enough not to fight the photo for
   attention. The earlier problem was the text competing with the whole
   photo; this fixes it by darkening only the strip the text occupies, not
   the photo itself. */
