/* ==========================================================================
   ROLLBACK PASS. ID8 is a front door to the tools right now -- not an
   agency site, not a résumé, not an AI company. One typeface (Inter),
   warm white + near black + one accent color. Five-step hierarchy, all
   the same family, nothing inventing its own capitalization or scale:

   1. ID8 (.hero-mark)            -- largest, the brand.
   2. Ideas in Motion (.hero-tagline) -- secondary, quiet.
   3. Section titles (.section-title) -- Tools / Contact, one shared rule.
   4. Tool names (.tool-module-name)  -- what you'd click.
   5. Descriptions / body (.hero-descriptor, .tool-module-desc, footer)
      -- smallest, dimmed.
   ========================================================================== */
