/**
 * CSP-safe expression evaluator for SSR templates.
 *
 * Evaluates a tightly scoped subset of JavaScript expressions against a
 * binding context without using `eval` or `new Function()`. Runs in any
 * runtime (Bun, Deno, Node, browsers) and is safe under strict CSP without
 * `'unsafe-eval'`.
 *
 * Supported grammar (operator-precedence Pratt parser):
 *
 * - Literals: numbers, single/double-quoted strings, `true`, `false`, `null`,
 *   `undefined`.
 * - Identifiers and member access (`a.b`, `a['b']`, `a[0]`).
 * - Optional chaining (`a?.b`, `a?.[b]`).
 * - Unary `!`, `+`, `-`, `typeof`.
 * - Binary `+`, `-`, `*`, `/`, `%`, `==`, `===`, `!=`, `!==`, `<`, `<=`,
 *   `>`, `>=`, `&&`, `||`, `??`.
 * - Ternary `cond ? a : b`.
 * - Parentheses for grouping.
 * - Function calls `fn(arg1, arg2, ...)` (only on identifiers / member chains
 *   resolved against the context — no arbitrary expression invocation).
 *
 * Anything outside this grammar throws a parse error which the caller
 * converts into the standard SSR fallback (`undefined`).
