   One file, used by every page, so the whole app looks and behaves the
   same everywhere.

   BRAND NOTE FOR WHOEVER PICKS THIS UP LATER:
   These are NorthernSky Studios' real brand colors, taken from the
   official Brand Guidelines PDF (section 04, Color Palette): Accent
   Teal, Ink, Paper, and Surface Gray. Teal is the one primary action
   color — links, buttons, highlights, the logo's darker swoosh stroke.
   Navy is not a guideline-specified UI color; it's kept here only as
   the dark surface behind the reversed (white-on-navy) logo lockup, on
   the sidebar and the Stakeholder View header, matching the guideline's
   own logo-variation rule for dark backgrounds. Because every color in
   this app is a CSS variable, changing them here updates the whole
   product — no hunting through pages.
