feat: binary micro-interactions across the page

Section headlines are written out behind a column of digits, mono labels
resolve from binary, the portrait assembles itself from bits, section indexes
rattle and keep one bit alive, cards get corner marks, the header shows the
scroll position as an eight-bit number, pressed links and buttons shed a few
digits, and the work stage leans towards the pointer. All effects respect
reduced motion and leave the content readable without JavaScript.

+## Motion (binary micro-interactions)

+- Building blocks live in `apps/web/src/components/bits/`: `DecodeText` (mono labels resolving from digits),
+  `BitWipe` (headline revealed behind a column of digits), `BitReveal` (picture assembling from bits),
+  `BinaryTicker`, `ScrollBits`, `BitBurst`. Reuse them instead of inventing new effects.
+- `DecodeText` is for monospaced text only; in proportional type the changing glyph widths make text jump.
+- Never put an in-view trigger on an element that clips itself away (clip-path): a fully clipped element
+  never counts as visible. Observe an unclipped wrapper (see `BitWipe`).
+- Every effect must respect `prefers-reduced-motion` and leave content readable without JavaScript.
