/* Instruct-Online: brings every old page and CGI screen onto the main site's colour scheme.
   Injected by Apache (apache/iol-theme.conf) into every old .htm page and every CGI response.

   v1.8 change of policy (Nate): every page uses the main scheme, so the lesson and test screens
   no longer show their per-course colours (IOL-1 kept them; that is reversed on purpose).

   How it works without breaking old layouts:
   - One reset with zero specificity (:where) sets text and background colours everywhere; any
     more specific rule below wins over it.
   - Old colour attributes (bgcolor, text, link, <font color>) and FrontPage theme images are overridden.
   - Widths, heights, positions and line-height are never changed: many screens use fixed tables. */
