/* ============================================================
   CID & ENGEL STUDIO — v9
   Piel de la v7 (tinta azul + cobalto + ámbar, barra azul,
   constelaciones) con la mecánica de la v8.

   TEMA DOBLE: el sitio sigue al navegador. Todo el color sale de
   variables. Si quieres cambiar un color, cámbialo en el bloque
   1.A (claro) o 1.B (oscuro) — nunca más abajo.

   ⚠ El juego oscuro está escrito DOS VECES a propósito: una para
   quien tiene JavaScript (atributo data-theme) y otra para quien
   no (media query). Si editas uno, edita el otro.

/* ---- frase que rota: va DENTRO del renglón, no encima ni debajo ----
   Tres detalles la mantienen alineada, y los tres importan:

   1. vertical-align: bottom. Una caja en línea con overflow oculto cambia
      su línea base al borde inferior; con el `baseline` de siempre el texto
      salía disparado hacia arriba. Pegándola al piso del renglón, no.
   2. height y line-height iguales al interlineado del párrafo (1.65), para
      que la caja ocupe exactamente un renglón y ni lo estire ni lo encoja.
   3. ancho fijo: el de la frase más larga, que el JS mide una vez y guarda
      en --rot-w. Así el texto vecino no se mueve al cambiar de frase.

   Si algún día agregas frases, no toques nada: el ancho se vuelve a medir
   solo. Sólo cuida que la frase más larga quepa en el renglón.            */
