style: CSS foundation for minimalist UI redesign

Adds the spacing scale, status-pill tokens, and a set of new utility classes
that the per-screen commits will use:

- spacing scale: --space-1 through --space-9 (single source of truth for
  vertical rhythm; replaces ad-hoc rem values throughout the .svelte files)
- status pill tokens: --color-status-{open,closed}-{bg,fg} (dark-mode aware,
  closed pulls from the same warning palette as .fb-banner--closed)
- .fb-shell.fb-page-narrow + .fb-page-center for vertical-centred narrow
  shells (landing + login)
- .fb-back-link — quiet text-only back-link, replaces the chip-style button
- .fb-inline-error — quieter alternative to .fb-banner--error
- .fb-toggle / .fb-toggle__{text,label,hint} — label-left + checkbox-right
  boolean fields (no UI library)
- .fb-status-pill / .fb-status-pill__dot / --open / --closed — clickable
  pill that toggles status
- .fb-menu / .fb-menu__{btn,panel,item,divider,item--danger} — native
  <details>/<summary>-based ⋯ menu, no JS framework needed
- .fb-card / .fb-card__{head,title,actions,meta} + .fb-card-grid — minimalist
  card on the gradient page bg, no border + shadow stack, generous padding
- .fb-empty — generous empty state
- .fb-share-strip / __url / __placeholder / __replace — inline header strip
  for the detail page, replaces the standalone Share section
- .fb-closed-line — neutral muted closed-state line for /f/[slug]
- .fb-segment / __btn / __btn--active — small segmented control matching
  .fb-tabs (for inline Visual/JSON toggle on Edit tab)
- .fb-detail-head / __title / __actions, .fb-tab-body, .fb-version-note,
  .fb-save-row — detail-page header + tab-body layout primitives

Also normalises:

- .fb-section margin-bottom 1.75rem → var(--space-7) (≈ 2.5rem)
- focus-ring opacity 0.15 / 0.25 → 0.2 across .fb-input + .fb-btn for a
  single consistent focus treatment

No structural .svelte changes here — only CSS additions and three numeric
edits. Existing pages continue to render exactly as before; the per-screen
commits that follow consume these classes.
