/* ---------- Contrast fixes (2026-09-12) ----------
   Aurora's global rules leak wrong colors into YCTheme surfaces:
   - h1-h6 { color: var(--bs-heading-color) } and strong { color: var(--bs-black) }
     override inherited panel text colors inside dark panels (.yc-cta, .yc-fit-panel,
     .yc-stack-core).
   - .fbs__net-navbar assumes a dark hero image behind it; YCTheme pages use light
     hero backgrounds, so its white brand/links are invisible.
   - .btn forces a solid primary background on every button variant, breaking
     .btn-outline-primary.
   The rules below restore readable contrast without touching the vendor files. */
