   corporate.css — shared chrome for the KPIcons Corporate site.

   Loaded by every page in /KPIcons Corporate/. Carries the tokens,
   typography utilities, masthead, footer, theme toggle, button system,
   section-header pattern, pullquote + CTA bands, and responsive rules.

   Page-specific layout (loop steps on index, pricing tiers on pricing,
   role grids on about, etc.) lives in each page's own <style> block
   so this file stays small and cacheable.

   Theme:
     - Default: warm paper (cream + deep-ink + gold accent, editorial)
     - [data-theme="dark"]: ink newsprint (deep navy + cream text)

   MOBILE HAMBURGER + DRAWER
   ------------------------------------------------------------
   The dropdown-style inline nav collapses at ≤640px. In its place,
   corporate-menu.js injects:
     • .masthead-hamburger  — the toggle button (lives inside the
                              nav, CSS-shown only on small screens)
     • .masthead-drawer     — a fixed full-viewport overlay that
                              slides down from the top and lists
                              every MENU entry as a big tappable row

   The drawer mirrors the MENU spec — flat links + grouped sections
   with sub-descriptions and a footer carrying the demo CTA so
   mobile visitors never lose access to a navigation surface.
