  16) Fix GPU 100% su ?r=online_calls (audit 2026-05)
  ---------------------------------------------------------
  PROBLEMA: app.css animava `box-shadow` (onlinePulse/onlinePulseWarn)
  sul ::before di OGNI riga "live" della tabella. box-shadow non e'
  compositor-only -> ogni frame = repaint. Con N righe (per=200) e il
  .panel contenitore con backdrop-filter, ogni repaint forzava il
  ricalcolo del blur dell'intero pannello -> GPU al 100% (Firefox).

  FIX (3 interventi combinati):
   A) Animazione compositor-only: transform:scale + opacity invece di
      box-shadow. Gira sul compositor GPU SENZA repaint. transform su un
      flex-item NON tocca il layout (niente reflow): zero rischio.
   B) Si anima SOLO lo stato RINGING (badge-warn): pochi, transitori.
      Le righe ANSWERED (badge-success) hanno il dot statico -> elimina
      ~tutte le animazioni simultanee, e toglie anche rumore visivo.
   C) Il .panel della tabella (.panel-flat, classe aggiunta nella view)
      perde il backdrop-filter: niente piu' moltiplicatore di costo.

  17) Fix GPU 100% — chartShimmer (audit 2026-05, confermato)
  ---------------------------------------------------------
  CAUSA CONFERMATA dal profiler Firefox: lo shimmer delle barre
  grafico (.chart-bar span::after, app.css) animava
  `background-position` in `infinite`. background-position NON e'
  compositor-only -> repaint per frame; il RefreshDriver restava
  al 99% e il Paint al 84% (categoria Graphics). Dentro un .panel
  con backdrop-filter ogni repaint moltiplicava il costo -> GPU 100%.

  FIX: si rimuove del tutto lo pseudo-elemento overlay (display:none).
  La barra resta col suo gradient di base (.chart-bar span) -> resa
  pulita, niente animazione, ZERO repaint continuo. Nessun impatto
  sul layout: il ::after era position:absolute/inset:0.

  Cleanup dello stile "gel/glassmorphism" preesistente:

    - via le shadow grosse colorate (16-36px = "lifted gel" 2020)
    - via il transform on hover (cliche' "il pulsante si solleva")
  Sostituiti con:
    - colori solidi (palette brand invariata: accent blu / danger rosso)
    - shadow micro (1-2px) solo dove serve depth
    - hover = darken via filter brightness, ZERO movimento
    - focus-visible ring accessibile (2px accent + 2px offset)
    - font-weight 600 (era 800: troppo pesante)
    - transitions 150ms con easing morbido
  Tutto in theme.css per non toccare app.css. Rollback = togliere
  questa sezione.
