Replaces the visible header copy of the supported-hardware section
with t('landing.boards.*') keys:
- label "Supported Hardware"
- titleLine1 / titleLine2 ("Every architecture." / "One tool.")
- subtitle (the "19 boards across 5 CPU architectures..." paragraph)
The five engine cards underneath (avr8js, rp2040js, QEMU lcgamboa,
QEMU Xtensa, QEMU ARM) and per-board specs (e.g. "ATmega328p · 32 KB",
"RP2040 + WiFi") deliberately stay in English — those are accurate
technical specs / product names that don't translate, and mixing
locales inside a spec line would hurt readability more than it
helps.
