Launch /industries/telecom and refine its hero and copy - #322

The stage's overflow-hidden, there to keep its dot field and glow inside the rounded edge, also cut off the Standardize tiles while they drop in from above the frame. Only the decoration layer clips now; the stage overflows.

- Hero: the third headline line sets at 0.9em in regular weight, keeping
  its gradient. The headline column is capped at 9.5em so the three lines
  break the same way at every size.
- Hero: the artwork shows from 1024px up, at a width that scales with the
  viewport.
- Hero: the bottom fade is 64px on phones, so the third line stays readable.
- Network: the Network Functions line drops "telecom" so it sets on two
  lines like the others.
- Pillars: the Integrity line now ends "across environments".

The pillar cards' side padding is reduced so the text column is wide
enough for the Integrity line to wrap to three lines at desktop widths.
