Replace every em dash with real punctuation (rewrites, not hyphen swaps) in docs, code comments, scripts, configs, and the port records; convert en dashes, curly quotes, ellipsis glyphs, arrows, and section signs to ASCII; drop machine-writing tell phrases from living docs. ADR titles now use a colon. The M2 bring-up DTS model string carried an em dash into the patch series and its record echoes; fixed at both, and the full series re-verified to apply cleanly onto pristine 6.18.46. One comment in freshness.h deliberately names the em dash glyph the UI renders as the unknown mark; that is data, kept as prose naming it. Verified: cargo tests (sim, config-lint, rs485-bridge), shellcheck, both driver MC/DC harnesses, patches-apply.

RV1106 6.18 driver parity vs the 5.10 vendor kernel
Goal: every driver the panel's 5.10 kernel runs must work at ≥ parity on our
self-built 6.18. Source of truth = the running 5.10 system on warden-c8a3
(lsmod + /proc/interrupts, captured 2026-08-24). Verify each on hardware via
the A/B _b-slot loop (../docs/m2-boot-on-c8a3.md); [x] means confirmed on
c8a3, not just compiled.
