Rewrite copy (positive tone) + redesign target grid

- All section copy rewritten: solution-first framing, no 'klagesang'
- Hero: 'Selvhosternes registrar. Bygget af jer. Kostpris.'
- Section order: target identity first, then what we build, then background
- Rename 'Problemet' → 'Baggrunden', 'Idéen' → 'Hvad vi bygger'
- Remove all victim language (tvinger, mod din vilje, ingen teknisk gevinst)
- Target grid: drop colored backgrounds/borders, clean bordered grid
  with row separators, blue checkmarks, muted dashes — no template feel
- Fix inline color styles → CSS classes (.required, .optional)
- Footer: slight copy improvement
