* draft(tui): add theme interface and Claude/Codex presets proposal
Introduces the Theme interface alongside the initial specifications and styling models for the Claude (card-based, warm) and Codex (high-density, split-screen cyberpunk) layout presets. Detailed design plans are documented in docs/THEMES.md.
* fix(tui): implement Claude/Codex themes on the existing palette system
theme.go had replaced the tuiTheme/buildTheme/palette architecture every
renderer depends on with a standalone Theme interface using the wrong
lipgloss import, breaking the build and orphaning the existing theme
registry, /theme command, and picker.
Revert theme.go to the working implementation and add claude and codex
as real palette entries in theme_palettes.go, following the file's own
extension pattern. Both pass the WCAG AA contrast and gray-ramp
invariants asserted across the whole registry, and are picked up
automatically by --theme, ZERO_THEME, /theme, and the picker.
Rewrite docs/THEMES.md to describe the actual palette-registry
architecture instead of the removed interface.
* fix(tui): rename Claude/Codex to neutral Dune/Neon, ensure WCAG AA contrast compliance, and add tests
* style(tui): gofmt theme_select_test.go (drop trailing whitespace)
The ubuntu smoke run fails on gofmt -l; this clears the only unformatted
file in the draft so CI goes green.
* test(tui): cover the CLI/env resolution path for the dune and neon presets
TestNewThemePresetsWired only checked lookupTheme and the IsDark
grouping. Add coverage for the actual --theme/ZERO_THEME precedence
path (resolveThemeMode) and confirm applyTheme swaps zeroTheme to each
preset's own palette rather than a built-in fallback.
* fix(tui): raise Dune/Neon palette contrast and fix theme docs
Darken dune's accent, blue, and red tokens so the selected-row caret,
local-model dot, and diff deletion text clear WCAG AA against selBg and
delBg, including after ANSI-256 downsampling. Also correct THEMES.md's
description of bare /theme (it opens a live-preview picker, not a
list), and add the dune/neon names to the ZERO_THEME/--theme tables in
README.md and README_ZH.md.
* fix(tui): keep Dune and Neon readable after ANSI-256 downsampling
- Dune's accent becomes #724028: still AA on selBg and panel in truecolor
(5.46:1 and 7.03:1), and its xterm-256 quantization (#444444) now clears
AA on quantized selBg at 6.47:1 where the previous #7c4712 quantized to
#875f00 at 3.81:1. Blue already survived quantization at 4.67:1.
- Neon's diff bands move to hexes that quantize to distinct green and red
xterm entries (addBg #083c10 -> #005f00, delBg #3c0810 -> #5f0000,
addBgWord #147828 -> #008700, delBgWord #74202e -> #870000) instead of
collapsing to the same grays, while keeping every truecolor invariant.
- New TestExtendedThemeANSI256Contrast quantizes the palette tokens the way
a 256-color terminal does and asserts the Dune selected-row pairs stay AA
and the Neon bands keep their green/red identity and mutual separation.
- docs/THEMES.md is now linked from the Documentation sections of both
READMEs, and the Unreleased changelog inventory says twelve themes and
names dune and neon.
* fix(tui): keep Neon diff content AA after quantization, fix error border
- faintest becomes #74c468: line numbers now quantize to #87d75f, which
clears AA on the xterm-green addBg (#005f00) where the old #58af69
quantized to 2.95:1, while staying dimmer than faint so the gray ramp
stays monotonic.
- addInk becomes #ecffdc, quantizing to #ffffd7 for 4.60:1 on the word
band's #008700 (was 4.29:1). Both rendered diff-content pairs are now
asserted in the ANSI-256 test instead of documented as omissions.
- cardErr becomes #9a4042: 3.01:1 against the panel (2.43:1 before) and
3.65:1 quantized, meeting the 3:1 non-text component threshold, with the
border surface asserted in both renderings.
- docs/THEMES.md no longer claims the extended invariants run against the
whole registry: it now says new palettes must be added to the
per-palette contrast tests or given equivalent coverage.
