/* AERIS RGB: canonical neutral restyle (preview, self-contained).
   Neutral dark base with glass, Arial, 5-8px corners, text-style buttons.
   The product colour (mint #74f0b3, the page's existing accent) is the single burst:
   eyebrow numbers, focus, pressed states, link underlines, dividers' tick, the lock panel.
   The loudest colour on screen stays the visitor's own light in the 3D canvas. */

/* Support launcher clearance (replaces the old Ask Frank bubble rules).
   The site-wide /assets/frank-chat.js loads button.em-support-launcher: position:fixed, bottom-right, 58x50 at 12px up to 520px wide, 129x50 at 16px from 521px.
   The page adapts; no rule here selects or restyles the launcher. --launcher-safe = launcher width + its offset + air (78px compact, 160px full).
   Text, links, inputs and buttons never sit in that right-hand strip, so nothing is under the launcher at rest, mid-scroll or at the end of the page.
   At 761-1100px the right gutter is 160px (>=140px required). --launcher-clear shrinks toward the normal gutter once the centred column leaves the strip on its own. */
