/* L'ESPONENTE NEGATIVO CHE SPARIVA (segnalato dal founder, 2026-08).
   In notazione scientifica "10^{-7}" il meno dell'esponente non si vedeva: la formula si
   leggeva "10 7". Il meno di KaTeX (U+2212 in KaTeX_Main) e' una barra orizzontale sottile,
   e alle dimensioni tight (KaTeX porta gli apici a .7em) la sua altezza scende sotto il
   pixel: l'hinting fa collassare i due bordi sulla stessa riga di pixel e non resta NIENTE
   da disegnare, nemmeno un antialias.
   Misurato a 1x contando i pixel scuri nel rettangolo del glifo, al variare della dimensione
   del testo contenitore da 12 a 30px: con font-size 1.05em spariva a 12/16/16.5/17px — e 16px
   e' esattamente la dimensione delle opzioni e della risposta. NON e' un errore di scala: ogni
   moltiplicatore ha una sua banda cieca (1.10em → 15-16px, 1.15em → 14.5-15.5px, 1.21em, cioe'
   il default di KaTeX → 14-14.5px). Il problema non e' quanto e' piccolo il testo, e' che una
   barra spessa mezzo pixel a volte non si arrotonda a niente.
   Un filo di contorno sulle sole parti tight garantisce l'inchiostro a ogni dimensione (nessuna
   banda cieca fra 12 e 30px) senza ingrassare visibilmente la formula. `currentColor`: eredita
   il colore del testo, quindi vale identico in tema chiaro e scuro. Dove -webkit-text-stroke
   non e' supportato si torna al comportamento di prima: nessuna regressione. */
