//! The baked panel font: font8x8, printable ASCII, shipped as data.
//!
//! In-panel `Text` marks on a pixel target need glyphs without a font stack, and
//! glyphs are LUT data, not code. Coverage is honest: printable ASCII draws,
//! everything else advances without ink (the same degradation contract as
//! unsupported charsets elsewhere).

/// The 8×8 bitmap for a printable ASCII char — 8 rows top-down, bit 0 the
/// leftmost pixel — or `None` outside `0x20..=0x7E`.
