refactor(website): cut the stock patterns out of the design

Audited against the AI-design catalog. The world stays — the terminal
aesthetic, the oxide accent, IBM Plex Mono are all chosen, and the audit
cleared them. What went is the handful of defaults that had crept in
underneath it.

Eight feature cards at identical weight said every feature mattered equally.
Search is what the client is for, so it takes a double-width cell and the
grid drops to three up; eight cards plus that one double still comes out
square.

Each glyph sat in a 34px bordered square — the stock icon-in-a-chip
treatment that ships with every component library. The glyphs are the real
TUI's, so they now sit inline like the prompt markers they are.

Callouts lose the coloured left rule. The catalog puts it plainly: a
coloured left border is about as reliable a sign of generated design as an
em-dash is in prose. The tone already lives in the label, which was saying
the same thing twice.

Thirteen arrow glyphs were typed into labels and link text. The
leaving-the-site mark belongs to the control, not the copy, so Button draws
it once, aria-hidden, and only when the link actually leaves. The "read
more" arrows on internal links were pure flourish and are gone.

The hero also drops "blazingly fast Rust", which TONE-OF-VOICE.md lists
under banned, no exceptions.
