/* ── Solstice standalone shell palette (Phase 1 light-mode sweep, 2026-07-31) ── Replaces the identical `:root { --brand-* … }` block that was copy-pasted into 25 shells (theme remediation P5 carve-out: "shell pre-auth --brand-* literals stay — render before stylesheets exist"). This sheet keeps that guarantee — it is a static in each shell's , so it applies before first paint with NO dependency on the ERP sheets — while retiring the 25 drifting copies (they had already drifted: --surface #1a1d27 vs canonical --sol-bg-card #1a1d24; canonical wins, per the P2 rule). How the two states work with ONE value set and NO light branch here: · Pre-auth (PIN pad, loading): the ERP sheets are not injected yet, so the var(--sol-*) references resolve to their dark literal fallbacks → the shell renders the charcoal brand chrome exactly as before. · Post-boot: solstice_shell.js/solstice_login.js inject token_system.css and set body[data-mode]/[data-site-theme] from `solstice:mode`, so the same aliases resolve through the canonical registry — including its Paper-warm light branch — and the shell chrome follows the mode with no second palette to maintain. --brand-glow stays a literal amber alpha (accent, deliberately mode-agnostic). The gradient composes from the aliases so it follows too. Consumed by every shell's own
