/* ============================================================
   Albert Academy — company + trainer profile page
   The corporate credibility page Thai HR/L&D reads before booking.

   DESIGN CONTRACT
   ---------------
   * LIGHT conversion style (Albert, 2026-08-25): cream base, dark text,
     gold accents. Black/navy ONLY as bookends (nav, method band, footer).
     All-black-and-gold long-form is hard to read and is not used here.
   * Component DNA is inherited from ai.albert-academy.com — the gold pill
     label, the short gold rule under a headline, pill buttons, card grids —
     so the two properties read as one company. The PALETTE is inverted
     (cream ground instead of navy ground) per the rule above.
   * Brand v1 typography: Oswald for English caps, Anuphan for Thai body and
     headings, Kanit Black for the ONE loudest hook (the hero h1) and
     nowhere else. Kanit is not the general brand font.
   * Mobile-first. Base styles target 390px; media queries add up from there.

   CONTRAST NOTE — do not "fix" this back.
   #D4A935 gold on cream is ~2.2:1 and fails as body text. Gold is used for
   FILLS, rules and icons; gold TEXT on light ground uses --gold-ink
   (#8A6510, ~5.1:1). The bright gold only carries text on dark ground.
