== Runtime required-capability detection ==
PASS  mbstring is tracked as a required capability
PASS  curl is tracked as a required capability
PASS  all required capabilities present in this environment
PASS  preflight detects missing mbstring (required-not-ok)
PASS  preflight detects missing curl (required-not-ok)
PASS  preflight passes when all required present

== Text sanitisation (iconv available) ==
PASS  iconv is available in this environment
PASS  sanitised text is valid UTF-8 (iconv path)
PASS  sanitised text keeps café
PASS  sanitised text drops control chars

== Text sanitisation (iconv unavailable — guarded fallback) ==
PASS  scrub without iconv does not fatal and returns a string
PASS  scrub without iconv yields valid UTF-8
PASS  full sanitise via fallback keeps café
PASS  full sanitise via fallback drops control chars

== mbstring-safe wrappers ==
PASS  has_mbstring true here
PASS  strlen counts codepoints (café = 4)
PASS  substr is codepoint-aware
PASS  truncate adds an ellipsis by width

== Renderer mbstring/iconv guarding ==
PASS  renderer no longer calls mb_strlen/mb_substr directly
PASS  fit_text uses calee_calendar_strlen/substr
PASS  ascii works with iconv (transliterates)
PASS  ascii works without iconv (no fatal, pure ASCII)
PASS  ascii without iconv strips non-ASCII
PASS  degraded renderer yields a 1200x630 PNG for a multibyte name
PASS  no unguarded mbstring/iconv calls in runtime code

All dependency self-tests passed.
