Wire the custom-theme editor end to end. In AppearanceSettings, when the
"Custom" theme is selected, show a "Start from current theme" button, a "Dark
theme" polarity toggle, and a grouped token grid (SURFACES / TEXT / ACCENT /
STATUS / OTHER) of 11 base tokens. Each token is a swatch that toggles an
inline ColorPicker; edits route through AppearanceState.custom-set-token
(drag) and custom-set-token-hex (hex commit).
The crate::custom_theme controller reads the base straight from the editor
swatch properties (the in-memory source of truth, no per-drag disk reads),
sets the touched field, re-derives via qbz_theme::theme_from_base, pushes the
palette live and persists. seed_from_current snapshots the live Theme global
into the base; toggle_dark flips polarity; set_token_hex parses in Rust (Slint
cannot). main.rs registers the four callbacks.
Also harden the ColorPicker reseed guard: skip decompose when the fed-back
value equals our own emitted color, so a drag ending at v=0/s=0 no longer
resets the hue. New strings added to all 7 gettext catalogs (es Mexican/
neutral); msgfmt --check clean; full .slint tree validated via the slintcheck
stub.
