/* scroll-scrub.css — cinematic scroll-scrub landing template (cinematic-landing skill).
   Canvas frame-sequence hero pinned via position:sticky, captions ride on top.

   BUILDFLOW RESKIN — cambios sobre el molde (documentados, nada estructural):
   1. Variables de .ss-root recoloreadas a la marca BuildFlow (orange/teal/ink)
      + fuentes Poppins/JetBrains Mono self-hosted (ver buildflow.css @font-face).
   2. `font-weight:700` agregado a los selectores "display" (Poppins Bold no es
      un solo peso ultra-black como Bebas Neue/Archive Black del molde original,
      hay que pedirlo explicito).
   3. `.ss-kicker` y `.ss-stat` pasan a --mono-stack (var nueva, aditiva) —
      convención de marca: micro-labels y numeros SIEMPRE en mono tracked-out.
   4. `.ss-video-spacer` baja de 720vh a 520vh/380vh (conversor corto, no
      catalogo — ver plan seccion "Ajuste al molde").
   Las 9 reglas inviolables del molde (RAF loop, .ss-root anchor, ready-antes-
   de-updateLoaderUI, cero overflow-x:hidden, singleton guard, onerror→warn)
   quedan intactas — cero cambios de estructura ni de JS.

   NOTE: do NOT add overflow-x:hidden on html/body/.ss-root or any ancestor of
   .ss-video-stage. Any ancestor with overflow != visible breaks position:sticky
   for its descendants (the canvas detaches and scrolls away instead of
   pinning) — that is what caused the black-void scroll bug, twice. There is
   currently no horizontal overflow source in this layout (verified live:
   document.documentElement.scrollWidth < window.innerWidth), so the rule
   isn't needed. If horizontal overflow ever appears, fix the specific
   offending element (e.g. clamp its width/margin) instead of reintroducing
   this rule on an ancestor. */

/* SCRIM POR ESCENA — agregado sobre el molde (2026-07-27).
   El molde original se probo con metraje oscuro (Breezely) y le alcanzaba el
   text-shadow. Este hero es metraje real con neon brillante: medido frame a
   frame, la luminancia p90 detras del texto llega a 187 en 4 de las 6 escenas
   -> el texto blanco se lava. Un velo global mataria la imagen, asi que el
   scrim es LOCAL: una elipse suave detras de cada bloque de texto, transparente
   en los bordes. Oscurece donde hay que leer y deja limpio el resto.
   `isolation` mantiene el z-index:-1 dentro de la escena (queda sobre el canvas
   y debajo del texto). .ss-scene es DESCENDIENTE del stage, no ancestro, asi
   que esto no toca la regla del sticky. */
