Dated tech comparisons that end with a verdict for a concrete context — because the honest answer is always "it depends", so each analysis spells out what it depends on.
Real decision analyses from real projects — not neutral feature matrices. Each document:
- anchors to a concrete context — a "Context" section up front; the verdict claims validity only for that profile,
- compares honestly — including the rows where the losing side wins,
- ends with a verdict once complete — the option actually chosen, with the accepted trade-offs spelled out; analyses still under way are marked ⏳ in the table below,
- is a dated snapshot — facts carry a verification date and the document is not retro-updated.

English is canonical. Analyses that originated in Czech keep the Czech original alongside (README.cs.md). Drafts still in progress may exist in Czech only until the English version is written.
