/* ==========================================================================
   LUFLY - HERO "Crafting Water"
   --------------------------------------------------------------------------
   A full-bleed cinematic first screen. One photograph (per category) runs
   under the transparent navbar; the copy, the scroll cue, the category
   selector and the trust strip float above it.

   House rules:
   * the hero pulls itself up under the sticky navbar, so the photo really
     runs underneath it while the navbar is transparent;
   * only transform / opacity are animated (the side handoff, the Ken
   Burns drift, the entrance cascade) - all compositor work;
   * prefers-reduced-motion: no autoplay zoom, no entrance cascade, a short
     plain fade only;
   * logical properties throughout, so a future RTL locale mirrors itself.

   15. Launch sequence - the Explore Collections button
   --------------------------------------------------------------------------
   The one showpiece animation on the page - but a FAST one: the whole
   show is over in under half a second, so the click never feels held
   back. A plain left click on the primary CTA starts it (hero.js
   intercepts the click, adds .is-launching to the section root, then
   navigates):

     t=0     the arrow ignites - it flips to bright ink with a teal halo
             (it is about to travel over the photo, where the dark
             resting ink would disappear) - pulls back a touch, then
             follows a tight decaying orbit of ~2.5 turns while a teal
             comet-arc (the vortex) spins behind it
     t=100ms the photograph starts receding (dim + a gentle zoom)
     t=140ms copy, scroll cue, tabs and trust strip start cascading out
     t=460ms hero.js hands over to the catalogue - the exit fades keep
             running while the new page loads, so the handover stays
             smooth even on a slower server

   The arrow stays crisp and readable through the orbit - no blur, no
   cover; the spin itself is the show. Everything is transform / opacity
   on composited layers. Modified clicks (ctrl/cmd/shift/alt), non-left
   buttons and prefers-reduced-motion visitors never see it; hero.js
   leaves those to the browser. The resting button carries none of this:
   every rule below lives under .is-launching.
