/**
 * Shared "needs EC driver" gate shown in place of Thermal/Battery/Sensors
 * tab content when `check_ec_status` reports the CrosEC driver is missing.
 * The Expansion tab does not use this gate — bay occupancy is plain USB
 * enumeration and works without EC access per ARCHITECT.md's Tier 1/2 split.
 *
 * No install button here, disabled or otherwise: the only driver that could
 * unlock this (DHowett's community CrosEC driver) isn't signed for normal
 * use — installing it means enabling Windows test-signing mode and
 * disabling Secure Boot, which also triggers a BitLocker recovery-key
 * prompt on next boot. MainFrameWork won't automate or casually prompt for
 * that trade-off, so this screen states the real reason instead of
 * implying it's a "coming soon" build-it-eventually gap. See
 * installer.rs's doc comment and SECURITY.md for the full explanation.
