 --- Custom statusline (heirline via astroui.status components):
----   left  = NvChad style: mode pill with separators, file info, git branch/diff
+---   left  = NvChad style: angled mode pill, file info pill, git branch/diff
----   right = VSCode style: diagnostics (NvChad icons), LSP, Ln/Col, Spaces,
+---   right = VSCode-style info modules, ending in an NvChad mode-colored
----           encoding, EOL, filetype — flat text, no powerline chunks
+---           progress pill (nerd font icon + Top/Bot/percentage)
+---
+--- NOTE: every nerd-font PUA glyph in this file is written as a \u{XXXX}
+--- Lua escape ON PURPOSE — raw 3-byte PUA glyphs (U+E000-U+F8FF) have been
+--- stripped by tooling before, silently flattening the statusline.
+--- Keep this file ASCII-only.
