Detailed Description

File-scope panel context.

Static allocation only; we keep one panel per build. cfg is copied from the caller-supplied descriptor at ra8_epaper_init.

vcom_verified is the INV-VCOM-1 permit: it is the single piece of state that decides whether ra8_epaper_display_area is allowed to bias the film at all. It is cleared at init and set only by a ra8_epaper_set_vcom whose readback matched what was written, so no sequence of calls can obtain the permit without the controller having confirmed the value.

Invariant: vcom_verified implies vcom_mv is the magnitude the controller echoed back, and state is k_ra8_epaper_state_ready.
