v1.10.0

Added — {{phone}} base tag

• New first-class {{phone}} base tag (cross-source like {{email}}/{{text}}, in includes/tags/phone-tags.php) that outputs a stored phone number, by default wrapped in a tel: link. The number is read from a meta/option field via the standard field-read path, so it works in every source: src:site → wp_options / ACF-options; src:current/unset → post/term meta; src:ref / srcTermIn → traversed-entity meta (list mode). Key-required in every source (no use enum).
• tel: href is rebuilt from the stored value, preserving the author's separators. Unlike {{email}} (whose href is the address verbatim), the tel: href is normalized into a canonical dial value. Hyphens appear in the href only where the author wrote a separator — (987) 654-3210 → tel:+1-987-654-3210, but bare 9876543210 → tel:+19876543210 (no fabricated grouping). The display text stays the stored value verbatim; only the href is reformatted. (Display-side formatting is a planned follow-up.)
• Country code resolves 2-tier: an in-field international prefix (+… or 00…) wins; otherwise the global Settings → Tag Extensions → Phone → "Default country code" (digits only, empty default) is prepended. With no country code and no in-field prefix, a national tel: link (no +) is emitted — fine for single-country sites. A leading national trunk 0 is stripped when a country code is applied (e.g. UK 07911… → +44-7911…). The country-code setting field shows worked-example placeholder text and links a country-code reference.
• Separated leading country code is auto-deduplicated. When a +-less number carries the global country code as its own author-separated first group (1-800-555-1212, 1 (800) 555-1212, 1.800.555.1212 with country code 1), the number already contains the code, so it is treated as international and the global code is not prepended again — → +1-800-555-1212, never a doubled +1-1-800…. The author's separator is the disambiguating signal; this never fires on a flat bare-digit string.
• Optional unseparated leading-country-code strip (global Phone → "Strip unseparated leading digit(s) matching the default country code", default OFF) covers the harder, separator-less case the auto-dedupe cannot — a code run together with the national number and no + (e.g. 18005551212 with country code 1). With no separator there is no way to tell a real code prefix from a national number that begins with the same digits, so this is opt-in and warned. Matches the configured global country code only.
• Default-ON tel: wrap toggled by noLink (inverted bare key — absent = wrap, present = plain text), and visibility-gated off a/button/img/picture, mirroring {{email}}. Cross-source list mode (limit/sep) wraps each valid number individually. A fallback phone number fires only when no valid number resolves. Unparseable numbers (assembled digit count outside 7–15) are skipped this release.
• Media-block safety backstop (also applied to {{email}}). The native visibility gate cannot hide these tags on the GB media block — that block's tagName defaults to "" and never serializes (its enum holds only img), so the value-compare leaves the tag offered, and GB then injects the output into the <img src>, corrupting it. Both callbacks now detect a generateblocks/media host block and emit nothing, so the default-on link wrap can never break an image. Editor-picker UX (hiding the tag in the selector there) is tracked in #35; the GB constraint is documented in docs/gb-constraints.md.
