   Company page hero — narrow-phone line-break fix
   (scoped to body.company-page only; does not touch .hero-sub-br,
   .company-statement or .lead-text on any other page)

   Below 480px, the statement and lead paragraph use fixed, hand-placed
   line breaks instead of relying on the browser to auto-wrap. Auto-wrap
   (with or without text-wrap: balance) depends on exactly which font is
   painting the text at layout time — the intended web font (Noto Sans
   JP) once it has loaded, or a fallback (Hiragino Sans, Yu Gothic, the
   platform's default CJK font, etc.) while it is still loading, or on a
   browser that doesn't support text-wrap: balance at all — and
   different fonts measure Japanese characters slightly differently, so
   the exact same CSS can land its automatic line break mid-word on one
   phone/browser and not on another. This was confirmed directly: swapping
   in Hiragino Sans / Hiragino Kaku Gothic ProN / generic sans-serif
   reproduced the original mid-word splits even with the previous
   fine-tuned max-width in place.

   Fixed <br> tags remove that dependency entirely — the line breaks are
   identical no matter which font actually renders. .hero-sub-br (the
   PC/tablet forced breaks) is hidden here as before; .company-mobile-br
   marks the additional break points used only below 480px. Both are
   plain presentational <br> elements in the markup — the sentence text
   itself is unchanged.

   max-width is intentionally left unset here (the base rule's 560px /
   720px is already far wider than any phone viewport), and text-wrap:
   balance is dropped — both were only needed to influence where the
   browser's *automatic* wrapping fell, which fixed <br> no longer needs.
   Each fixed line was measured to stay well under the narrowest target
   container (~327px at 375px) across Noto Sans JP and its fallbacks, so
   none of them wraps again on its own.
