/*
    File: style.css
    Progetto: maldev.it - restyling one-page
    Data creazione: 17/09/2026
    Autore: Lorè
    Descrizione: Stile completo del sito (header, hero, servizi, come lavoriamo,
                 chi siamo, gallery, FAQ, portfolio, contatti, footer).
                 Design token nei :root, mobile-first, breakpoint 768/1024.

    Aggiornamento 17/09/2026 - Lorè
    Applicata palette Maldev: accento #ea265a, grigio medio #878786,
    testo scuro #2a2a2c, footer #1f1f21. Rimosso sabbia warm dal bg-alt.

    Aggiornamento 17/09/2026 (2) - Lorè
    Aggiunto stile honeypot .hp-field e feedback form (.form-feedback).

    Aggiornamento 17/09/2026 (3) - Lorè
    - Logo header 3x (34px -> 88px), header alto 110px via var --header-h
    - Logo footer 3x (32px -> 96px)
    - Hero con immagine come background sezione (rimossa colonna .hero-visual)
      + overlay chiaro per leggibilita', testo su singola colonna centrato verticale

    Aggiornamento 17/09/2026 (4) - Lorè
    - Portfolio: celle piu' grandi (min-height 220px, padding 3rem)
      e loghi ~3x (max-width 260px, max-height 160px). Card cliccabile con hover translate.

    Aggiornamento 17/09/2026 (5) - Lorè
    - Selettore footer .footer-col h4 -> .footer-col .footer-heading (HTML ora usa <p>)

    Aggiornamento 17/09/2026 (6) - Lorè
    - .btn ora inline-flex con align/justify-content:center per centraggio testo
      robusto (risolve "Contattaci" non centrato su mobile con flex:1)
    - Portfolio mobile: aggiunto override .client/.client img con dimensioni
      ridotte (padding 1.5rem 1rem, img max 130x80) per evitare overflow
      orizzontale che tagliava la seconda colonna a 2 colonne

    Aggiornamento 17/09/2026 (7) - Lorè
    - Portfolio: grayscale+hover ora dentro @media (hover:hover) and (pointer:fine).
      Su touch (mobile/tablet) i loghi sono sempre a colori, dato che :hover
      non e' un'interazione disponibile/scopribile su schermo touch.

    Aggiornamento 18/09/2026 - Lorè
    - Aggiunto stile .legal-page/.legal-content per privacy.html (testo lungo,
      leggibile, coerente con la tipografia del sito). Vedi sezione LEGAL PAGE in fondo.

    Aggiornamento 18/09/2026 (2) - Lorè
    - Aggiunto .identity-grid/.identity-block: 3 blocchi (Chi siamo/Filosofia/
      Il nostro metodo) affiancati al contenuto esistente in #chi-siamo, sotto
      about-grid, separati da bordo superiore. Testo riscritto al plurale
      agenzia (era in prima persona singolare nella bozza originale).
