   HumanOfOneMCP — the public site.

   Tokens come from the mark itself (h1-mark.svg): warm paper, #1C1815 ink and
   the #EA5600 the figure is drawn in.
   The wordmark's spaced uppercase monospace is the display voice; IBM Plex Sans
   carries prose; mono also marks anything that behaves like data — a rating, a
   domain judgment, a derivation.

   Three theme states: explicit light, explicit dark, and the default where only
   prefers-color-scheme speaks.

   A five-column research table in a 325px window needs 650px and hides half of
   itself. Horizontal scrolling is a fine escape hatch for one wide row; it is
   not a way to read eighteen.

   So below 640px a `.stacks` table stops being a table and becomes one labelled
   block per row: the header is hidden and each cell carries its own label from
   `data-label`. The reason column — the part that actually matters here — gets
   full width instead of 40% of a sideways scroll.

   Opt-in rather than global: a two-column key/value table already reads fine
   stacked and gains nothing from the treatment. */
