feedback5 WE1: the 「治疗生命值低于50%」 module heal compares HP as its client buff does — 华法琳 / 闪灵 ≤, 瑕光 / 古米 / 塞雷娅 / 录武官 < (follow-up 19)

PRTS gives only the display text; the client's module buffs decide (local [uc]equips.ab + buff_template_data, extracted
2026-10-06): 瑕光 / 古米 / 塞雷娅 GUA-X set_heal_scale_by_hpratio (FilterByTargetHpRatio LT), 录武官 reckpr_e_002_tr (LT),
Touch acmedc_e_tr (LT); 华法琳 bldsk_e_002_tr and 闪灵 shining_e_003_tr — like 黍's GUA-X and 凯尔希's PHY-X —
heal_scale_up[hpratio][LE].

- kits/shared/tier4.js installLowHpHealBonus and tier5.js lowHpHealUp take { atOrBelow }; 华法琳 (tier 4 and 5) and 闪灵's
  PHY-X heal ×1.15 at or below 50 %; the strictly-below kits keep `<` and cite their template.

Golden: no scenario moved (no heal of the corpus lands on an ally at exactly 50 % HP).

Tests: test/content/feedback5-lowhp-heal.test.js (new, 2); kits_t4, kits_alt_t4, kits_t5, kits_alt_t5, op_shining,
standin_acmedc pass.
