/* Hero headline: one continuous left-to-right mask reveal that
   travels from the very first word to the very last, in reading
   order. .headline__line is a block wrapper per authored line
   (forces the same two-row layout as before, and lets long lines
   wrap naturally on narrow screens). Each word inside it gets its
   OWN positioned .headline__word box — this matters because a mask
   spanning a whole (possibly wrapped) line clips by raw horizontal
   position, not reading order: if a line wraps into two visual rows,
   words starting at the same x-position on different rows (e.g. the
   first word of each row) would reveal simultaneously. Masking
   per-word avoids that entirely, since each word's clip-path is
   scoped to its own box regardless of which row it wraps onto.
   Inside each word: a .headline__ghost sits in normal flow at 5%
   opacity (defines the word's box + always-visible "watermark" text),
   and a .headline__reveal is an absolutely-positioned, fully-opaque
   duplicate clipped with clip-path. Every word shares one
   GPU-accelerated clip-path animation; each word's own
   animation-duration/-delay (set inline, roughly proportional to its
   length) chain back-to-back with zero gap and zero overlap, so each
   word's sweep picks up the instant the previous one finishes —
   reading as a single unbroken sweep through the whole sentence. */
