Remove dead mode-home type tokens superseded by --text-hero

[BigSimmo]

Summary

Follow-up cleanup to #517. Removes the dead stepped mode-home type tokens that #512 added, now that #517's hybrid-fluid hero (--text-hero clamp() + the existing -minus tokens) replaced their only consumer.

Removed from the globals.css @theme block (zero references anywhere in src — confirmed by git grep):
--text-xs-plus, --text-sm-plus, --text-base-sub, --text-2xl-sub, --text-3xl-sub, --text-3xl-plus, --text-4xl-minus, plus their now-orphaned scale comment.

No visual change — those tokens generated text-* utilities that nothing used. This reconciles the two parallel token sets left after the #517 / #512 merge.

Verification

• prettier, check:type-scale --strict, check:icon-scale, lint, typecheck — all green.
• The globals.css merge-artifact guard unit test passes (6/6).
• git grep confirms zero usages of the removed tokens across the repo.

Clinical governance preflight

N/A — CSS token cleanup only; no ingestion, retrieval, answer generation, source rendering, document access, privacy, or production-config changes.

📝 Walkthrough

Summary by CodeRabbit

• Style

  • Streamlined typography settings by removing unused text-size variants.
  • Retained the shared fluid hero scale for compact layouts.

• Documentation

  • Updated type-scale guidance to reflect the completed backlog and stricter validation.
  • Clarified that arbitrary text sizes are rejected by the type-scale checks.

Walkthrough

The global Tailwind theme removes obsolete mode-home typography documentation and several custom text tokens. Process-hardening documentation now records the shared fluid hero scale, removed aliases, and strict type-scale gate enforcement.

❌ Failed checks (1 error)

Check name	Status	Explanation	Resolution
Verification Claims	❌ Error	PR description says “prettier, check:type-scale --strict, check:icon-scale, lint, typecheck — all green,” which is a vague verification claim, not exact run/result wording.	Rewrite verification notes as exact command/result pairs, e.g. “Ran npm run verify:cheap: passed” or “Not run: reason.”

✅ Passed checks (10 passed)

Check name	Status	Explanation
Title check	✅ Passed	The title is concise and accurately describes the main change: removing unused mode-home type tokens.
Description check	✅ Passed	The description is mostly complete, with summary, verification, and governance notes that match the template's intent.
Docstring Coverage	✅ Passed	No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check.

Risky Git Or Deployment Actions	✅ Passed	Only a type-scale docs note changed; no force-push, reset --hard, destructive clean, rebase, or unsafe deploy guidance was added.
Supabase Project And Schema Safety	✅ Passed	Only a docs note changed; no Supabase project refs, env examples, migrations, RLS/policy, or schema/data changes were introduced.
