//! Panel specification for GDEQ0426T82 (4.26" 800x480 Monochrome e-Paper display).
//!
//! ### Hardware Notes:
//! - **Seeed Hardware**: Seeed Studio Product 6398 (4.26" Monochrome SPI ePaper Display)
//! - **Controller IC**: SE8350 / SSD1677
//! - **Native Resolution**: 800 x 480 pixels (already byte-aligned, no RAM padding)
//! - **Y-Axis Reversal**: panel gates are physically wired in reverse; `Ssd1677Controller`
//!   compensates for this in software (see its `set_window`/`set_cursor` implementation), so
//!   this is transparent to callers.
//! - **Busy Polarity**: Active-HIGH (busy while HIGH).
