   NAVBAR OFFSET — LOS 52px DEL NAVBAR FIJO
   #darnel-banner va en position:fixed (custom.js:227), así que el
   layout tiene que cederle 52px o el navbar se monta sobre el
   contenido. El offset estuvo primero en body{padding-top:52px}
   inline; como la app mide 100vh, ese padding se sumaba FUERA de la
   caja y medido: documentElement.scrollHeight = clientHeight + 52 y
   window.scrollY = 52 en 1024x768, 1180x820, 1366x768 y 1920x1080.

   Probado y descartado sobre #root: no tiene altura propia (medido
   height 820 = hijo 768 + padding 52) y su hijo lleva h-screen, o sea
   otros 100vh fijos.

   Lo toma el contenedor real del layout, del bundle compilado de
   Chainlit 2.11.1:

     div.group/sidebar-wrapper.flex.min-h-svh.w-full
       > div.h-screen.w-screen.flex

   El padding va en el wrapper, que ademas declara min-h-svh: con
   box-sizing:border-box el alto total se queda en 100svh y el padding
   se come espacio por dentro en vez de crecer el documento. El hijo
   .h-screen es height:100vh FIJO, asi que hay que encogerlo a mano:
   sin esto el wrapper mediria 52 + 100vh y el scroll fantasma
   reaparece (medido 820 = 768 + 52).

   El offset se acota a las pantallas con navbar: custom.js:198 sale
   temprano en /login y ahi no hay banner que estorbe. Se usa :has() en
   vez de una clase en <body> para no depender del orden de carga; la
   hoja ya lo usa en form:has(#chat-input) y
   div.relative.w-full:has(#chat-input).

               burbuja max-width 95%, table 11px
     769px  -> pastilla visible, gutter 16px, burbuja 100%,

   20b. ANCHO DE COLUMNA ESCALONADO — TABLET 10"/12" Y PC
   Chainlit fija la columna con un max-width INLINE
   (min(48rem, 100vw) = 768px) en dos elementos: la lista de
   mensajes y el wrapper del composer. Ese valor no crece nunca,
   ni en 12" ni en PC.

   Medido antes del cambio (ancho de la columna / espacio muerto):
     768×1024  10" portrait   -> 768px  (0 lateral)
     834×1194  10" portrait   -> 768px  (33 lateral)
     1024×1366 12" portrait   -> 768px  (128 lateral)
     1180×820  12" landscape  -> 768px  (206 lateral)
     1024×768  12" landscape  -> 768px  (128 lateral)
     1366×768  PC             -> 768px  (299 lateral)
     1920×1080 PC FHD         -> 768px  (576 lateral -> 40% de uso)

   Un max-width con !important en la hoja de estilos pisa el inline
   (el !important de autor gana a un inline sin !important), así que
   basta con pisar estos dos contenedores. El .step es hijo directo
   de la lista, por lo que los mensajes siguen a la columna.

   24. BOTÓN DE VOZ — PRIMER HIJO DE LA FILA DEL COMPOSER
   custom.js (sección 5b) mete #darnel-floating-mic como PRIMER hijo
   de la fila real del composer — el mismo div.relative.w-full donde
   vive #chat-input, el mismo ancla que usa moveSubmitButton() para
   sentar el enviar. La fila queda entonces
   [ micro ][ #chat-input ][ #chat-submit ]
   con el gap 8px que ya impone el flex. No hay position:absolute ni
   offsets: el ancho del enviar deja de importar y no hay nada que
   recalcular a mano en cada breakpoint.

   Antes el micro era hijo absoluto de #message-composer, posicionado
   con una escalera de right: calc(...) (68px / 76px / 72px según
   peldaño) más top:-26px en ≤640px. Medido a 1920x1080: micro en
   [1340,942,56,56] sobre el extremo derecho del textarea
   [464,942,932,56], y el texto solo se salvaba con el
   padding-right: 76px reservado. En ≤640px el override
   top:-26px / right:12px daba un solape 44x18px con el enviar.
   Sin offsets, el solape es imposible por construcción.

   El textarea vuelve a su padding natural (12px 20px, línea 485) y
   al 20px de ≤640px: el micro ya no invade el texto.

   position: relative + z-index 50: el contenedor era el ancla de las
   ondas ::before/::after (absolute, margin -28px, z-index -1) solo
   por ser absolute. Al volver a estático se anclarían a
   #message-composer, se dibujarían en el centro del composer y el
   z-index -1 las mandaría detrás de su fondo. position: relative no
   altera el layout flex y devuelve los anillos centrados en el botón.

/* ================================================================
   27. DIÁLOGO DE CONFIRMACIÓN — NUEVO CHAT
   Reutiliza el lenguaje visual del selector de máquina (sección
   10): mismo fondo oscurecido y mismo backdrop-filter. El z-index
   va a 10000 porque tiene que quedar por encima del banner, que
   va a 9999 inline (custom.js) y 1000 por CSS, y por encima del
   overlay del selector, que va a 9997.

   Diferencia con el selector: aquel es align-self:flex-start con
   overflow:auto y mide lo que mide su contenido, y por eso había
   que scrollear la página en viewports cortos (ver el bloque de
   max-height:860px más arriba). Este es un panel de altura fija y
   corta, así que va centrado en ambos ejes. El margin:auto del
   panel es lo que lo mantiene centrado cuando aun así se pasa de
   alto, en vez de recortarse por arriba.
