   Use these tokens and classes everywhere (home page and case studies).
   Raw hex codes, px font sizes and one-off shadows belong here only.

   COLOR (by role: never use a background token for text, or vice versa)
     Backgrounds   --color-bg-white       bright white (button hover fills)
                   --color-bg-paper       off-white page / hero desk

                   --color-bg-card        card panels on the dark section
     Text          --color-text           black text on light backgrounds
                   --color-text-inverse   white text on dark backgrounds
                   --color-text-muted     secondary text on dark
                   --color-link           links on dark
                   --color-signature      handwritten signature
     Borders       --color-border-subtle  card edges on dark

                   --color-border-strong  button outlines on dark

     Elements      h1–h4, p and small get these by default.

                   .text-lead .text-body .text-small .text-caption
                   .text-muted — use these to give any element a role's look
                   regardless of its tag (e.g. an h2 that looks like .text-h3).
