Ayu, as close to the original as pardes draws: ayu_dark, ayu_mirage, ayu_light

+//! Ayu Dark: Ayu, as close to the original as pardes can draw it.
+//! Every value is the original's own, cited on its line (path:line key); the
+//! chrome pardes needs and the original lacks is derived from its palette.
+//! Sources:
+//!   palette (themes/*.yaml, generated src/generated/*.ts); url https://github.com/ayu-theme/ayu-colors; genizah ~/05-genizah/ayu-colors; commit b0fd979a1ddf050101b43311fa598a1a9c5f1bbc
+//!   VS Code port (roles, terminal colours); url https://github.com/ayu-theme/vscode-ayu; genizah ~/05-genizah/vscode-ayu; commit d676974ebb245fa5a7ae4444027f72801017f1b6
+//! Tags: the tab (focused = the active tab, unfocused = the inactive one).
+//! Adjusted to meet pardes's floors (chrome only; text, syntax and ANSI are untouched):
+//!   - focused tag ground #10141c -> #33363b: 1.03:1 off the unfocused #0d1017, pardes needs 1.5:1 on a dark page
+//!   - unfocused tag text #5a6378 -> #747c8e: 3.16:1 on #0d1017, tag text needs 4.5:1 to be read and run
+//!   - rules between panes #1b1f29 -> #393b42: 1.12:1 off the page, lifted toward the text to 1.6:1 (as colors.zig separatorOf does)
+//!   - scroll thumb #2e3441 -> #313743: 1.48:1 on its track #10141c
+//! Upstream notes: Roles from vscode-ayu's generated ayu-dark.json (bordered
+//! variant, the one package.json ships as the default); syntax roles are its
+//! tokenColors and each is checked equal to ayu-colors syntax.* in
+//! src/generated/dark.ts (that file is ayu-colors' own generator output: `npx
+//! tsx scripts/generate-themes.ts` run in the genizah checkout; it resolves the
+//! OKLCH l1..l5 steps and -L/A modifiers of themes/dark.yaml). type =
+//! tokenColors "Entity name" (scope entity.name, covers entity.name.type; there
+//! is no entity.name.type rule). number and constant share syntax.constant.
+//! status_* from VS Code statusBar.* (one status bar: status_nc_* null).
+//! tabline_* from tab.*; tabline_fill = editorGroupHeader.tabsBackground. Alpha
+//! composited over editor.background (selection, line numbers, cursorline,
+//! split, scrollbar thumb). scroll_track null: VS Code has no track key
+//! (transparent over the editor). search_fg, selection_fg null: not set.
+//! info/hint null: neither vscode-ayu nor ayu-colors defines an info/hint
+//! colour (VS Code falls back to its own defaults). accent = focusBorder =
+//! common.accent.tint. ansi is vscode-ayu's terminal.ansi*
+//! (src/template.ts:458-473: normal = syntax.* darken(0.1) except green =
+//! vcs.added, black/white/brightBlack from a fixed table at template.ts:5),
+//! which differs from ayu-colors' own terminal.* section (listed in palette as
+//! terminal.*). palette = every colour of src/generated/dark.ts; alpha entries
+//! composited over editor.bg (editor.*) or ui.bg (others); skipped shadows:
+//! ui.panel.shadow, ui.popup.shadow.
