Struct WhitespaceConfig 

pub struct WhitespaceConfig {
    pub show: bool,
    pub tab: Option<char>,
    pub trailing: Option<char>,
    pub leading: Option<char>,
    pub space: Option<char>,
    pub eol: Option<char>,
    pub tabstop: u32,

2026-05-27: display.whitespace.* snapshot consumed by the cell-builder when emitting cells. Mirrors the option_cache.whitespace_* shape but lives here so the worker can be written without a config-crate import cycle.

show is the master gate (display.show_whitespace). When false, the builder emits whitespace bytes verbatim. When true:

• tab: glyph substituted for \t (None → leave as-is).
• trailing: glyph for spaces between the last non-space byte of a line and EOL.
• leading: glyph for spaces between BOL and the first non-space byte.
• space: glyph for middle (non-leading, non-trailing) spaces. None → keep middle spaces as ’ ’.
• eol: glyph appended at the visual end of each line. Reserved for a follow-up (extending past the last char complicates byte↔col remap).

Fields

show: bool

tab: Option<char>

trailing: Option<char>

leading: Option<char>

space: Option<char>

eol: Option<char>

tabstop: u32

W.4.t: columns a hard tab expands to. The builder advances each \t to the next multiple of this width, emitting that many cells (a marker glyph + space fill when show, plain spaces otherwise) so the cell grid models a tab at its true display width — one width model the host scroll model and both renderers share. 0 (the Default) is treated as 1 (legacy one-cell tabs) so test fixtures need no change.
