New Reference page "Generating sample data" (captured output + a two-table seed cast showing generation, FK sampling context, and a `set` override); cross-links from inserting-and-editing-data and columns; seed added to the rdbms highlight grammar; querying/sql-queries renumbered. Cast stance in STYLE.md revised to "justify the absence". Refs #33, #34.

// Minimal Shiki / TextMate grammar for the RDBMS Playground *simple-mode*
|
|
// command language, so docs code blocks fenced as ```rdbms get syntax
|
|
// highlighting. Advanced-mode examples use the built-in `sql` grammar.
|
|
//
|
|
// Keyword/clause vocabulary is taken from the in-app help/usage strings
|
|
// (`src/friendly/strings/en-US.yaml`) and the command grammar. Matching is
|
|
// case-insensitive (keywords are case-insensitive in the app; identifiers
|
|
// are case-preserving and intentionally left unscoped so they read as plain
|
|
// text against the coloured keywords).
|
|
//
|
|
// Two language ids share one grammar:
|
|
// - `rdbms` — real commands; gets a decorative `> ` prompt via CSS.
|
|
// - `rdbms-syntax` — abstract syntax templates (with <placeholders>); same
|
|
// highlighting, but a distinct `data-language` so the
|
|
// prompt (scoped to data-language='rdbms') is NOT added.
