/* =========================================================
   INTERACTION SYSTEM: one set of rules for "this is tappable".

   1  Text link    One style for every link inside a string: a DOTTED underline, same weight scale,
                   same offset, same colour as the text around it. Hover: the underline turns solid and the
                   text goes muted. No other signal (no bold, no colour, no icon), whether the link stays
                   on the site or opens a new tab. One exception: a link inside the h1 is plain until
                   hovered (then underlined, colour unchanged), like the project titles on the same page.
   2  Link group   Header nav and footer links: no underline, because their position says "link".
                   Hover: muted. In the nav, an underline marks the current page ("you are here").
   3  Block link   A whole row is the target and ends in an arrow (→ stays here, ↗ leaves).
                   Hover and focus: the arrow nudges and the title is underlined.
   4  Button       Icon or text <button>, or an action link such as Email (copies the address and
                   says "Copied"). Hover: muted. Hit area is at least 44px on touch screens.
   5  Chip         OUTLINED pill = tappable (none on the site right now).
                   FILLED pill with no outline = a label (tags, "Before/After", panel names), never tappable.
   6  Disclosure   A row with a chevron that turns (Experience).

   Cursor: pointer on everything tappable, default elsewhere. The cursor dot grows on the same set.
   Focus: one ring (2px var(--focus)) on all of them.
   If you add a new interactive thing, it must fit one of these six. Don't invent a seventh.
