/*
 * Design Threads -- module CSS
 *
 * Consumes platform tokens from platform/styles.css. Module-local tokens
 * are project-color derivatives via color-mix; the platform sets
 * --project-color per active project (falling back to --accent).
 * Yellow is reserved for --warning semantics in Strata, so the module
 * accent is intentionally NOT a gold/amber hue -- that role belongs to
 * the Re-verify badge below.
 *
 * Two tiers (per .claude/rules/modules-lessons.md preflight):
 *   Tier 1 (container-scoped): classes rendered inside the module
 *           container -- prefixed with [data-module="design-threads"].
 *   Tier 2 (modal-content): classes rendered in ctx.ui.modal({ content })
 *           HTML live OUTSIDE the data-module scope; rely on the .dt-
 *           class prefix as the leak guard. Added when modal flows land.
 */

/* --- Full-bleed override -------------------------------------------------
 * Same DAM / ai-renderings / product-catalog precedent -- the platform's
 * .strata-module-container caps at 1200px and centers, which would waste
 * horizontal real estate on the home list and the detail two-column
 * layout. :has() selects the outer .strata-content wrapper; the
 * combined class+attribute selector on .strata-module-container targets
 * the container itself (NOT a descendant -- :has() would not match).

 * by the platform per active project; falls back to --accent on no
 * project), with color-mix soft / line / row variants. The sample-tracker
 * module is the existing precedent for color-mix tinting.
