Repair `portfolio.html` into a polished, responsive portfolio page without
external libraries. Keep the three projects and links. Use semantic nav/main/
article landmarks, a fluid CSS grid using `repeat(auto-fit, minmax(...))`, a
mobile max-width breakpoint, visible keyboard focus, a viewport meta tag,
border-box sizing, reusable `:root` spacing/color variables, responsive images,
and a reduced-motion media query. Avoid a fixed-width projects container.
Only edit `portfolio.html`.

Repair `modal.html` into an accessible destructive-action modal without
libraries. The opener must expose its dialog relationship. The modal needs a
programmatic label, `role=dialog`, and `aria-modal=true`; opening moves focus
inside, makes the page main inert, and locks body scrolling. Trap Tab and
Shift+Tab within the modal. Escape, Cancel, and backdrop clicks close it,
restore background state and scrolling, and return focus to the opener. Give
the close control an accessible name and center the overlay responsively.
Only edit `modal.html`.

Repair `settings.html` as an accessible account-settings form without
libraries. Add explicit labels and appropriate email/numeric input hints.
Connect validation text with `aria-describedby`, announce errors, use native
constraint validation plus a positive plain-integer team-size rule, and clear
custom errors when corrected. Implement a light/dark theme toggle that updates
`data-theme` and `aria-pressed`, persists an explicit choice in localStorage,
and otherwise follows `prefers-color-scheme`. Add design tokens, visible
keyboard focus, and reduced-motion handling. Only edit `settings.html`.
