   Type    : 'Marcellus' (600/700 display, elegant spa-style serif) +
             'Karla' (body) — a botanical, spa-like pairing distinct from
             every prior build this session
   Motif   : AM/PM ritual — a sun icon glows, then a moon icon glows,
             representing the twice-daily application routine; distinct
             from every other signature used this session
   Layout  : HERO IMAGE ON THE LEFT
   Tone    : calm, botanical, honest that this is a nail and skin
             wellness oil — never framed as a fungal-infection treatment
             or cure
   Rules   : grids minmax(0,1fr) · flex min-width:0 · img max-width min(Npx,100%)
             mobile hero order = IMAGE first, then H1, then rest
             NO standalone "Important" alert callout section (per
             standing instruction) — safety notes are folded into body
             copy and the footer disclaimer instead
