/* ============================================================
   etags.css — Tuxii · Sistema de e-tags (etiquetas e-ink)
   ------------------------------------------------------------
   Las medidas de cada formato llegan como custom properties que
   escribe js/etags.js sobre el elemento .etag. Todo el layout se
   deriva de ellas con calc(), así el render es pixel-perfect a
   cualquier resolución nativa de panel.

   Variables por etiqueta:
     --etag-w / --etag-h        dimensiones del panel
     --etag-pad                 padding base
     --etag-name                tamaño final del nombre (ya escalado)
     --etag-name-base           tamaño de nombre del formato (sin escalar)
     --etag-price-num           tamaño de precio del formato
     --etag-num-base            base del número según estado (pre-ajuste)
     --etag-num                 tamaño final del número (post-ajuste de ancho)
     --etag-brand / --etag-weight / --etag-foot
     --etag-bar-w               ancho del código de barras
     --etag-right-pct           ancho de la columna de precio (layout fila)
     --etag-badge-size          tamaño del badge
   Paleta: --etag-paper, --etag-ink, --etag-gray, --etag-ink-c (tinta
   efectiva: gris en sin stock), --etag-band, --etag-band-text,
   --etag-badge-bg, --etag-badge-text
